General :: Bios Flash Boot Floppy
Apr 4, 2011
I am trying to flash my bios but they only supply an exe or a floppy image. obviosly I am not running windows to run the exe and I dont have a floppy drive. So I have been trying to copy the floppy image to a cd with little success.Size of boot image is 2884 sectors -> genisoimage: Error - boot image 'F1B.IMG' has not an allowable size.The way I understand it thats 4 sectors over the 1.44Mb floppy size? Is there a way I continue anyway? Seeing that I will be putting it on a cd I cant see that the size is going to matter

I'm looking for a way to make a bootable floppy that has drdflash.img, my flash utility and my bios file on it for a bios recovery disk. This is on a board that has a failed bios, so everything is pretty much dead (except for the humble floppy drive). I don't have a screen to work with so this floppy needs to be able to run the utility and automatically flash the chip for me. I've heard this is possible, but am unable to find clear instructions on how to do any of this. I know the basics of it is to copy the bios file and flash utility to a floppy along with a bootdisk that will run these things (sometimes the .bat file needs to be modified in order to do this automatically). So I've downloaded drdflash but it came as a .img and I don't think it can be 'just' copied to disk. I came across the 'dd' command but have also heard its nicknamed 'data destroyer' or words to that effect.

I have problem with my laptop Samsung VM7000. The BIOS has a password on which I don't know. It has no HDD and the CD-ROM is damaged. I have a FDD floppy drive and two USB slots, they work (tested). To remove password I tried this http://dogber1.blogspot.com/2009/05/...ered-bios.html but it didn't work.Then I've found a Linux based password cracker http://www.pccmos.com/ but, since my cd drive is dead, I can't launch it. I can write it on a flashdrive, but my laptop is not booting from flash, so I have to make a floppy-boot-disc to boot flash via floppy, but how?

I recently started to build a new box based on this board: [URL] All is going well enough except for very poor sound, and before I go any further trying to sort it out,it seems smart to update the bios as I am 5 or so releases back. The readme with the bios flash utility/file says to use a win98 boot disk + bios/utility floppy but the bios file itself is much too big to fit on a floppy anyway so I haven't been able to create a floppy-emulating cd as most discussions seem to suggest doing. I'm sure I'm missing something, but there has to be a way to take a win98 boot disk image, plus 2 files and get that to either boot from cd or better yet usb drive.

I probably have not done any serious programming for 20 years, not counting a little HTML.
I stumbled onto an old FREESPIRE disk my bro sent me several years back -- and tried installing it on a Sony Vaio PCG FRV 28 I had crashed a few years back. The Sony bios is still aboard, but old enough to not have USB "booting" as part of the boot menu. I don't even know if one can easily hack into the BIOS on an old sony Vaio but changing the BIOS would solve lot of problems.
Does anyone have any ideas or certain knowledge on rewriting or modifying the Master Boot Code or an idea on making my USB [with Ubuntu or any other Linux implementation visible] and bootable to the bios on powerup?

I am having a Promise TX4650 RAID controller & trying to create a driver floppy for installing the drivers. Also am using RHEL 5, I can create the driver floppy, but when I type "mount /dev/fd0 /media/floppy" I get error: "mount: mount point /media/floppy does not exist".Can I get the files in a format other than the ext2 floppy image, so that we do not need to use a floppy drive?There is a readme file inside the driver archive & you can use that as a reference.

I have several (small) bootable linux distros on USB sticks, and I would like to use them on several computers, some of which do not have USB boot support. Many of these also do not have a CD drive.In order to get around this problem I would like to create a bootable floppy disk that can load the system from the USB stick (similar to http://www.damnsmalllinux.org/wiki/i.../Boot_Floppies). I have found quite a few floppy images on the internet (like the one above), but I haven't yet got one that works and boots the USB sticks that I have (i.e. one that can boot Tiny Core).Is this actually possible (it seems to be, but I haven't got it to work yet) and does anyone know how I can do it?

I have an old laptop I'd like to try Bodhi linux on from a usb stick. I've got it installed running on a newer laptop so I know the usb install works. I've searched considerably & haven't found the dummy version of how to boot any distro on usb from a floppy. I have used a DSL floppy to boot Damn small on usb. Is there an easy way to boot Bodhi or any other linux distro that is on usb using the same floppy? I type dsl fromusb to get damnsmall to run. Bodhi fromusb doesn't work.

I've installed RHEL 5.3 on a Dell Desktop. I don't want to install GRUB to the MBR. Is there a way to boot up RHEL from a floppy?I've installed GRUB on to a floppy but not having much luck starting up RHEL. In the past Slackware has allowed me to startup the kernel from a floppy using LILO. I was hoping that there is way for RHEL too.

OS: Windows XP
Virtual Machine: Bochs-2.4.5
I want to learn some details about linux booting, so I begin writing a small boot program myself. Yesterday, I was writing a small boot program and planned to use it boot a Bochs virtual machine. The boot program is written in assembly language and compiled with nasm.I use bxiamge.exe in Bochs and create an floppy image called boot.img and configure the Bochs virtual host to boot from this floppy image. My question is how to write the compiled boot.bin program into the floppy image(boot.img)?

I scored a Dell poweredge 6300 from a local pawn shop. It has the capability to boot from cd-rom, but apparently not with isolinux, which is what the debian installer cd uses. I was able to boot to UBCD411 (Ultimate Boot CD, which uses syslinux), but didn't see any option to boot to a CD (maybe I'm missing something here?). I tried using the boot floppy from this site. I didn't expect it to work (it's from the Woody era), and it did not. I got a message that says SYSLINUX ver.XXXX CBIOS boot failed. I went to [URL].. and looked for a boot floppy image for Lenny, but apparently it doesn't exist. I did however find the boot floppy image for Etch.
To be honest, even if I did find the Lenny floppy boot image, I'm not sure how to use it to point the system to the installer CD. So, I have two questions:
1) Does anyone know of a boot floppy image for Lenny, or if I could use the Etch boot floppy image?
2) How would one boot from floppy, then point the system to the installer CD?
System info:
(4) Xeon Pentium 2 processors 500 Mhz
(6) UltraSCSI hard drives
(1) SCSI cd-rom drive
(1) SCSI dvd-rom drive
(1) Floppy drive
(1) 10/100 NIC
I'm open to any other suggestions as to how I could install Debian Lenny on this machine.

Situation- Laptop (2003 made Toshiba 2410) with dead secondary controller, so no CDDVD drive, BIOS does not support any form of booting from USB. Laptop has working floppy (had to repair it) distros that are good for older units like that that also support booting from diskettes, and then can mount and install from a USB CDDVD rom drive.

The system is 11.1 32 bit and used to work ok
All the drives function and mount normally under Parted Magic.
Sometimes a cd will mount after 15 mins or so but if it is ejected it will not remount. after that event the dmesg output is 3 times as long. As it is 35K chrs long it is too long to post!
I have changed hardware and cables with no effect.
I have run the repair option on the install disk. I get a cannot find floppy error
It also reports cups, hal, ntp & postfix as errors but if I select repair it still returns the same next time I run the repair routine.
It also says the bootloader is faulty if I select repair I go into an infinite loop so I exit with skip. Anyway the system boots ok and runs just fine apart from the cd/fdd/usb problem

I dual booted my system with Linux Mint on a Windows 7 operating platform. I later thought it would be better to use Ubunta as I am a newbie to the system and there is more help available. I tried to uninstall Linux Mint through Windows but I am not sure I did. I then installed Ubunta from a CD and the whole system crashed. I am now unable to boot beyond the BIOS screen and am using Ubunta CD to access the internet. I would be grateful if you could shed any light on what has happened. Unfortunately I have no separate boot up disc.

I want to be able to access an old pc at home from any computer but I don't want to leave the computer on all the time (I won't use it regularly and I don't believe in wasting energy just cause I can). I've heard that some bioses have wake-on-LAN but I have no other machine on the LAN that will be left on (apparently it's impossible to wake a computer from off the LAN???) so my solution is to buy a raspberry pi (perhaps there is something cheaper/better??) and leave that on that I can ssh to from anywhere and then wake my pc from there. Unfortunately my bios doesn't have a wake-on-lan function and so I'm hoping that I can update my bios to a version that has a wake-on-lan option (perhaps there is a better way?).

I have a problem with flashing a BIOS. I have to use PXE to boot the computer, which actually works fine through syslinux. I also managed to find a FreeDOS floppy image (1.44 MB) that will be booted using syslinux.
The problem is moving the BIOS rom on to the computer to flash. For roms that fit on to the FreeDOS img it works fine if I just add the rom and the exe for flashing to the floppy image. But one of the roms I shall work with is to big to fit even on a 2.88 MB floppy.
I found a "Howto: BIOS-Update per bootable CD (Method II)" for creating a bootable iso holding the DOS image and the additional files for flashing. Using a syslinux configuration like Code: default boot prompt 0 label boot linux memdisk initrd 20101201_091658.iso append iso the iso will be transfered to the client and I get an "A:>" DOS prompt.
According to the HowTo I should be able to switch to drive of the "cd" and access the rom file there. I've tried all drive letters, but all I get is "Invalid drive <letter>:.". I tried booting the DOS with more drivers (FDCD0001 as CD-ROM driver) but it says "No CD-ROM drive to use; XCDROM not loaded!". Additionally it promts: "SHCDX33A installed. o drives assigned. 2 drive(s) available." Here is the question:
How am I able to reach the files from the iso that are not included to the DOS image?
Or maybe there is another way to flash a large BIOS rom over PXE?

I installed a Raid 2+0 a couple of days ago with windows 7, and everything was working fine until today. I left my computer for a couple of hours and when i came back all i see is this black screen with a blinking cursor, then i tried everything on the bios but every time i tried to boot it kept stuck there, right after the bios POST.Then i tried changing the SATA ports, that was something that fixed similar problems on my old Mobo, but this is strange because this mobo has 1 week, and the HD's (2x seagate 500gb) have 2 days, so they should be fine.
Then i tried with my ubuntu lucid lynx live cd, it has saved my life many times, it always works flawlessly and i thought i could use it to restore the boot files, but i was very surprised when it failed as well, it pops a message saying something like "invalid user pwsuid "user: unknown"{0}". Tried it many times with no luck, only that same message...Now i managed to boot from a "slitaz" linux dist. thats about 30mb, it has many useful tools.I can see the partitions/HD's on the Gparted and mount applications, but i still i havent managed to mount the raid i had on my Windows 7 install, im a bit scared of losing data, and i dont even know how to do it.Is there any way to fix thisrom the slitaz live cd?Maybe i could mount the Raid and then restore the Boot files from the slitaz live cd? I have a windows image i could use on the Raid, and i could copy the image files to a partition, make it primary, active and bootable...I really dont know, maybe that wont help either because the ubuntu live cd couldnt boot, i really dont know what whats going on and what could be the cause of this... maybe a worm/virus

I have a USB flash drive, which is bootable and I would like to copy the whole drive to a different drive.Can I just do a low level dd copy between both USB memory drives, or do I need to make an ISO of the source, and then put that ISO on the destination? I figured I could ask in less time than trying, and exhaustively testing to make sure I had it right...

I have a laptop that I need to update the BIOS but I cant get into Windows. Here is what I want to do.I know I need a DOS boot able disk. I figured I would download the FreeDOS disk and just add a file to the iso and burn the ISO. So far I cannot do that and I don't know how or even if there is a way to do this. So the long of the short of it is I need a bootable cd that is dos based and has my BIOS update file on it.

I don't know about you, but I have found the linux kernel to read pretty much any usb drive or sd card, while many bioses, especially, when they are older fail miserably. Now if you got yourself a machine which bios cannot boot from your 16 giga stick, wouldn't it be possible to use linux as kind of a bootstrap, install it on a 1 giga medium, that the bios can boot from and then when the linux kernel is running, give control to the other media that you really want to boot from. This should be doable.
It is basically going from a running kernel and its inird to give control over to another grub or syslinux. Does anybody know if this exists already? Truth is that many bioses are just garbage, old and fail at pretty much all new hardware, so why not use a linux kernel as a crutch, to get away from this old piece of junk? I did similar things already with a software raid, where i had a machine that couldn't boot from a HD that was larger than 150 giga.
I installed a 10 gb HD to put /boot on it and then give control over to some "fancy 21st century technology that can boot from this HUUUGE disks" (as from my dripping from sarcasm voice you can tell that pretty much all BIOSes are a thorn in my side and a P.I.T.A. for me, too often they only do 30% of what I expect them to)

Is there something weird about the FLOPPY DRIVE on F12? Nothing associated with it works & I can't get an icon for it. Also the FLOPPY FORMATTER no longer works. (mine is an internal drive)- I had some really miner quirks with it in 10 but it worked. I had some workaround launchers that I used until an upgrade semi-fixed it. (It would give a false error that it couldn't run but did. I just ignored it.)
I tried to edit FSTAB to cure a problem of my BACKUP drive showing up twice*** so while I was in there I added the stuff for the floppy & it still doesn't work. If I try to mount it manually, I get the error that /dev/fd0 doesn't exist.I tried to find some info on it & it SEEMS that there MAY be a bug but I'm not sure as the info is a bit confusing as to just what version & such they are talking about. And there was also the problem that all the stuff seemed to be OLD or not related to my problem.I why I quite hacking at my system, is that all my workaround launchers & the formatter say that there are GNOME things missing & they can't run. So I figure that there is something missing or screwy already & that I'd better ask BEFORE I make things worse or actually break something.With the fact that floppies are about gone, it's getting to be not that big of a deal but I still find myself having to use them for repair purposes (albeit, not as much) & it gets to be a bit of a pain to fire up M$ just to do something like this.
*** It appears that the one in FSTAB was the one I needed, so where would the OTHER one be so I can get rid of it? Or at least make it auto mount.

I'm trying to boot an SD card on a notebook that does not have BIOS support for booting from the SD slot. Using various how-to's I've figured out how to add additional SD card modules to the initrd.img file on a bootable USB drive such that I can boot Linux installed on the SD card.
However, best I can tell, it loads the kernel and initrd.img from the USB and everything else from the SD card. What I really want is to load the necessary SD modules from the USB and then chainload the SD card such that whatever kernel is on the SD card is loaded instead. Is it possible to chainload to another bootable device after the kernel (with the SD module additions) has already been loaded?

I have a USB drive on which I want to install Arch Linux (using the installer, not unetbootin or something similar, as I want the drive to be persistent.) The computer from which I want to boot this USB supports booting from a USB floppy, not a normal drive. Is there any way for me to make a USB floppy on another drive and use that to boot the normal USB drive?
