If I change my sata mode from IDE to AHCI grub won't show (cursor goes to top left) when I power on my system. After that, I press the reset button and my grub shows ok.
So, to use AHCI I always have to use the reset switch button.

How to temporarily lock CPU speed or stop power management? There is no /etc/init.d/powernowd
View 4 Replies View RelatedI'm not sure this belongs in this forum as opposed to the hardware forum, but I do not beleive this is a hardware issue.I want to stop the scrren from blanking and going to power save. I'm running 5.3_x86-64 and I'm using the nVidia drivers direct from nVidia called NVIDIA-Linux-x86_64-96.43.13-pkg2.run.
So far, I'm added DPMS off in /etc/xorg.conf, removed all the screensaver packages and all the power management packagesbut the screen is still going blank after a time of inactivity.What else do I need to do? I can not allow the screen to go blank, there should be no screensaver or power management and the machine should stay in a completely awake and ready-to-use state at all times.
I'm coming over from Ubuntu and am experiencing the same power issue I had there, only there doesn't seem to be a setting in Gconf in Fedora like there was in Ubuntu that can fix it. You know how the system determines whether or not to hibernate based on the amount of time the battery has been unplugged? Well there's a bug in Gnome that makes it say I have only two minutes left on a full battery,
so if I ever unplug my laptop it immediately goes in to hibernation. Now in Ubuntu there was a Gconf Editor setting that could be changed so that it went by percentage, but this option seems to be gone in Fedora. I have Gconf Editor installed but I can't find the setting anywhere.
I have Fedora 15 gnome 3 installed on my new laptop. When my system runs on battery my power management keeps changing my screen brightness. It keeps dimming my backlight. In the GUI of Power Management I cant find any option to change this setting. How can I do that through Command Line
View 4 Replies View RelatedI have a laptop with windows vista installed on the internal hardrive.Last March I installed wanted to start to use linux so I brought a separate external hardrive partitioned it to enable media storage on one section and installed ubuntu on the other half. It works fine and so does the windows vista on my internal hardrive, however I have to have the hardrive plugged in to boot.Until now this hasnt bothered me, however I've recently started to take my laptop into university and cannot switch it off unless I have the external hardrive with me as I cannot switch it on without it.With it plugged in it loads up GRUB and then gives me the option to load either Ubuntu or windows vista, however if it is not plugged in when I power up it says GRUB loader failed.It also occured to me that if for some reason my external hardrive fails in the future I wont be able to use my laptop anymore.Has the installation of ubuntu (and GRUB) altered the MBR?
Is there some way I can edit the settings so that I can load windows vista without the hardrive plugged in, and then if it is plugged in I get the choice which one to load?
When power was restored after an outage, my server (running Ubuntu server 9.10) started back up & got stuck in the GRUB menu ("Version 1.97~beta 4" I think) - it didn't do that countdown & auto-select the top item like I'm used to. Just stayed there, and since the server is headless, I had to dig out my monitor & hook it up to see what was wrong.

View 4 Replies View Relatedhow do I tell grub to stop trying to boot based on UUIDs? I've been dealing with this for about two years now. I have this one system, a PowerEdge 1550, that for some reason WILL NOT boot using a UUID, and will only boot if I edit the first entry in grub, remove everything to do with UUIDs (completely delete the search line, replace root=uuid=[uuid] with root=/dev/sda1). I can't seem to make these settings stick and now with 10.10 there's no longer a menu.lst to edit. So, in short, I need grub to stop trying to boot based on a UUID. Absolute paths, baby. That's what I need.
View 3 Replies View RelatedI recently decided to install Ubuntu 11.04 on a 320gb hitachi sata hard drive. This is going into a new system with an Asus MB, AMD Proc, not sure if this matters. Anyway I can not set the bios to use ahci and see the sata drive. I can only use IDE mode with sata enabled. Asus support says to install ahci for os. If I boot into the USB install key and attempt to the install OS I receive a read/write error. I have another drive on IDE that has 11.04 on it and if I try to format the new drive and partition it with Disk Utility it fails with "Error formatting drive: error creating partition table: helper exited with exit code 1: error calling fsync(2) on /dev/sdb: Input/output error". I have tried to use dd and fdisk but I don't believe I need these until I do something else first just not sure how or where to look.

I have been running a dual-boot, Windows 7 and Ubuntu 10.10 system with the disks set for IDE with no problems. I have just attempted to change the disk system to AHCI and, whilst I can boot into Windows 7, I am unable to boot into Linux and get the error: "Alert! /dev/disk/by-uuid/5d773307-a046-40fa-ba29-728611bc7eed does not exist" I am new to Linux so am unsure where to go from here. I have reverted to IDE for the moment and it boots Ok.

Code:
Could not find kernel image: linux After some experimentation, I found that switching the SATA mode in the BIOS from AHCI to Native IDE solved the problem and installation is proceeding normally.
However, I want AHCI enabled. (I think, unless someone has a compelling reason why I shouldn't.) My web-searching suggests that if the system is installed in IDE mode, it won't boot if I switch to AHCI afterwards. Is this a common problem? Is there a workaround? Is it a motherboard issue?
I am about to do a clean install of 10.04 (64-bit) on a ThinkPad X201. The machine will only be running Ubuntu (i.e., no dual-boot). Is there any reason to use compatibility mode for the SATA boot drive, or will AHCI work fine?
View 2 Replies View Related/sbin/udevd --daemon eats about 10-15% of cpu which is quite high. I found out that it is caused by AHCI. If I turn it off in bios, udev takes only about 0-1% of cpu (which I consider normal). However turning AHCI off is deadly for Windows Vista (I have dual boot) - it always ends up with BSOD. Actually, I don't even know what AHCI does. Of course I found some information on the net but I didn't found whether there are some advantages for me. Is it worth 10-15% of cpu (consequently shorter battery life)? On the other hand, I have no interest in changing my bios settings every time I boot to Windows so it would be much confortable to have it turned on all the time. The best solution would be to find out why AHCI does this and how to configure udev to avoid it. And I don't know how.I have OpenSuse 11.2, kernel 2.6.31.12
View 1 Replies View RelatedHow can I force my kernel to use the ahci driver when both the ahci & sata_nv are built into the kernel.?
My MSI board bios doesn't have an option for "AHCI MODE". The only sata option that it has is "called "On Chip Sata" & is located under "Integrated Peripherals. Also, the only values available for "On Chip Sata" are enabled or disabled. If I choose the disabled option, the sata drives arn't found & bootup fails.
I tried to tell the kernel to use the ahci driver by appending kernel options to my Grub2 bootloader but they all failed.
(eg.) ahci, scsi=ahci, ata=ahci, ahci.=0 sd=ahci
sata_nv=no, sata_nv=0, sata_nv=none
The only thing I can think of that is left to do is to re-build my kernel with CONFIG_SATA_NV as a loadable module & CONFIG_AHCI as a build-in driver. With only the ahci driver available at boot, the kernel will have to use it or fail to boot.
One more thing I want to say is that my other computer with the ASUS motherboard uses the ahci driver & I have both the sata_via & the ahci drivers built into the kernel. However, it has a bios option for AHCI MODE.
(eg.) Southbridge VT8251

One of my 2 harddisks, a Hitachi HDS72101, is very slow, the driver is ahci.
Output of "hdparm -t /dev/sda":
/dev/sda:

I am using openSuSE 11.2 on a VGN-AR41L. I have also erased the preinstalled Home Vista (what a pleasure). Now to my problem. My system boots correctly but if I press the <ESC> key while booting I can see the following messages:
"Doing fast boot
FATAL: mbcache module not found
FATAL: ahci module not found

and the boot process continues normally.
Why this happens? Does this mean that I have a problem that I haven't discovered yet? Is it something that I can ignore? I am using SUSE Linux from version SUSE Linux 8 personal and although I am not a power user I have done my two desertions on this system and I am very happy with SUSE. I have bought SUSE Linux 8 Personal and SUSE Linux 10 all the other versions until today have been downloaded.
I have a HP Pavilion dv7-2230sa During boot I get a series of errors about ACPI and AHCI Conflicts, the result of which I have to dissable ACPI with acpi=off. However when acpi=off my wireless Broadcom b43 series refuses to enable the wifi. I just can't press the button that would enable / dissable the wifi.
The wifi is detected, the drivers and firmware are installed, however the light remains firmly in the RED.the ethernet works, sound works fine, There also seems to be an issue with the ATi/Radeon Driver being missing which is causing fatal errors at boot time and also some memory conflicts again causing fatal errors.
I have tried this laptop under opensuse 11.2 and now under opensuse 11.3M5 without sucsess - however to my dislike Ubuntu have managed to resolve this by accident between 9.4 and 9.10 but i wanna use opensuse not ubuntu i have asked them to tell me how they fixed it to share it with you but I am still plowing my way through their forum!

I want to run my Debian install in AHCI mode on my computer. It runs perfectly fine, all drivers etc work perfectly also. The computer itself is in RAID mode but with all 4 RAID channels disabled (I refuse to use any RAID arrays because I simply don't like them). However, my computer (Acer Aspire m3640/m5640, motherboard MCP73PV/630i) has greyed out the option for me to change the option from RAID mode to either IDE or AHCI. Since I do not use RAID at all, I want to change to AHCI but it is greyed out in the BIOS. This option wasn't greyed out before as far as I remember.
I also have Vista x64 installed on a SATA drive along with Debian all partitioned. I also have an empty IDE drive attached which will be used for another operating system AFTER I have changed to AHCI mode. The SATA drive has the boot flag. I use GRUB to boot the operating system. My BIOS version from American Megatrends is R01-A3 (not the latest one, but the one I need to use). My question is this, how could one possibly go about as to changing it to AHCI mode from RAID with the BIOS greying the option out. how to make the BIOS ungrey the option (if there is another option preventing it from being changed or if the harddrives need configuring etc). I am not particularly concerned if the drives need to be wiped.
I realized after spending some time performance tuning my mini Linux server that the hard drive is stuck in IDE mode, and I can't get the controller to be discovered in AHCI mode.EDIT: I should add that I'm running Vector Linux 6.0 Lite, which is based on Slackware 13.0. The Kernel version is 2.6.27.12.
The mobo in question is actually a small mini-ITX board from Foxconn. Here is a links to the specs:url.I use it for a media server, and so far the drive I'm using (Hitachi HDE721010SLA330) is working fine in IDE mode (apparently).
I have a strong suspicion that the crappy Foxconn BIOS supplied with the board is not initializing the Intel 945GC controller in AHCI mode. There is a BIOS entry for setting the controller to "Advanced", but I don't think it's doing the job.
Here is an "lspci -vvnn" of my system:
Code:
00:00.0 Host bridge [0600]: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub [8086:2770] (rev 02)

Is there anything I can do to get the drive/controller in ahci mode, or is the BIOS screwing me?
I am using Centos 5.4 on an Intel DG451D Main Board. Two SATA drives in RAID1 mode via the main board's built in AHCI controller. It seems to work just fine but I would like to be able to monitor the state of my drives and controller, especially during a re-build and make configuration changes etc if possible, so new drives can be added etc from within the OS. Is there a way to do this within Centos or am I stuck with using just the BIOS configuration system? Apologies if this is a stupid question - I am pretty new to this and have spent several hours trying to find a solution to my question but to no avail.
View 1 Replies View RelatedServer has DQ35JO board, 8GB memory, multiple SATA hard drives. It was happily running Fedora 10, and Fedora 9 before that. I downloaded and burned the F11 DVD, booted it, did an install which is:
-- delete the LVMs
-- create a 200 MB /boot on ext3, the rest of /dev/sda on ext3 as /
-- reformat the swap partition on /dev/sdb1
-- leave the other file systems alone (they are all ext3)
I chose no optional packages and let it install. It finished normally and got to the "click to reboot" screen. Now, my server is completely bricked. When I power it up I get a blank screen with a blinking cursor. I cannot even get to the BIOS, or boot my Fedora DVD, much less boot the boot drive.
Yesterday I was on my Windows computer doing homework. Once Football came on, I hit the Standby button on my keyboard and walked out of my room. Came back at halftime to discover that my system never went into Standby. I turned on my monitor and saw a bunch of code repeating. I don't remember it all, but it was something to this effect
Super Block not compatible with current BIOS
scanning for *insert system file here*.... not found
scanning for floppy drive... not found
scanning for cdrom1... not found
So I hit the restart button on my tower. When it restarted, I was brought back to the same screen. So I unplugged the power cord from my computer and counted to 10. I plugged it back in and this time I got my mobo logo screen and the system appeared to start up fine, until I got to the SATA drive scanning screen. When my computer would scan for my SATA hard drive, it would idle for several minutes, during which a series of periods (".") would show up until eventually I get a message that says: WARNING! - Something wrong with your hardware!
I have troubleshooted a number of things so far:
1) I took my SATA Hard Drive out of my computer and plugged it into my Linux computer and the system booted fine! I used the same SATA cord, so I know both the drive and the cord ARE WORKING!
2) I tested the power cord from the power supply that runs to my HD and it is working just fine.
3) I plugged the HD back into my Windows computer (the original one it was in when I started having this problem) and I ran GParted. When the GUI came on, I could not see any drives and there was a message at the bottom of the window saying that no devices could be found. This was no surprise to me because I watched the verbose mode as GParted booted and it gave error messages when it tried scanning for my hard drive.
4) I have also tried plugging it into the other SATA ports on my motherboard.
5) I tried flashing the mobo BIOS. The flash worked just fine (or at least it appeared so), but the HD is still not being found on the system boot scan.
Bottom line, I know the hard drive is fine because it worked in my Linux computer. So I am thinking it has to be the motherboard. But before I go out and buy a new Mobo and CPU (and possibly new RAM), I wanted to quickly jump on here.
