I converted a PXE boot environment to CentOS 5.2 (64 bit). It is used to install various flavors of Linux. The default timer within the menu is configured for 10 seconds. Can anyone recommend a version of syslinux that is compatible with CentOS 5.2 (x86_64) in which the menu timer issue has been resolved?
View 8 RepliesI installed Windows, then Ubuntu, but I don't know how to set the timer for the Dual-boot menu to start at Windows firstOn my Laptop, Ubuntu is set to run first and it's set to start after 10 secondsBut I wasn't the one who installed Ubuntu on my Laptop, it was someone else...etc. So I don't really know how to do the thingI want to set the Dual-boot so that Windows bee's the first one to start loading, at a timer of 1 minute

Warning Timer ISR/0: Time went backwards: delta=-252671169 delta_cpu=-248671169 shadow=6729603658291 off=235680520 processed=6730092000000 cpu_processed=6730088000000 0: 6730088000000
I installed centos 5.3 with last update in Virtualbox 3.06. Everything looks quite good except the unix time. It's very fast than normal. I even couldn't make ntpd work.

I also modified the menu.lst files as following: kernel /vmlinuz-2.6.18-164.el5 ro root=/dev/vg00/lv00 rhgb quiet divider=10 But it still dosen't work. how to sync the local time in the virtualbox? It looks like a bug in current kernel as other linux with newer kernel don't have such problem.
We're doing a web gui with extjs & flash chart. The problem is a drilldown menu from flash chart to some other page. The drilldown menu is working fine on all other os & browser, but not on 64bit centos 5.x & ff 3.0 or 3.5, which we need to support. It's always behind the flash chart. With the firefox coming with 64bit centos 5.x (which I believe it's a 64bit firefox), all of them are not working. But the weird thing is, with some newly installed centos 5.4, if I use a firefox 3+ downloaded from mozila/firefox official site (I guess it's a 32bit firefox).
The drilldown menu works fine. However with some other centos 5.4 which are upgraded from centos 5.2, the drilldown menu won't work. Please see the attached screenshots for the detailed info. I've tried many things, tried latest 32bit flash plugin, tried 64bit flash plugin, tried updating the nspluginwrapper (according to [URL]) and several other things. None of them works. From adobe tech note [URL].
"Note: The WMODE parameter is supported only on some browser/Flash Player version combinations. If the WMODE parameter is not supported, the Flash movie will always display on top. Refer to TechNote 14201 for details."
I understand that not all the os & browser & flash version combinations support WMODE, but it really bugs me that with almost the same os (64bit centos 5.4), the same firefox (32bit v3.5.5 downloaded from getfirefox.com), the same flash plugin (32bit v10.0.r32), why some of them can see the javascript menu on top of flash chart, but some of them will always be behind the flash chart?
I have some virtual machines running with CentOS 5.3 (32 bit) and everything works as expected. To test a possible upgrade I took one of then and did yum clean all yum update after rebooting I get a kernel panic with the following message:
MP BIOS BUG : 8254 timer not connected to APIC IO I know that I can change the boot command not to use APIC and after that the machine boots again but I doubt that there has been any change to the virtual APIC implementation during the upgrade of the OS. Is there anything that iI should exclude from upgrading while working in a vm? I use VMWare Player 2.5.3 build-185404 on a 64 bit Ubuntu 9.04 as host.
What can be the cause of this error.

3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?
Why is the timer not executing?
Code: #include <stdlib.h>
#include <unistd.h>
#include <stdio.h>
#include <signal.h>
#include <time.h>
#include <pthread.h>

But what I need to know is how do you set the timer so that if I don't press "Enter"...that it choses my preferred operating system in a certain period of time (seconds or minutes...etc) by itself?
How do I set the user inactivity timer to a different value in 10.04? It seems to be set by default to a very short time.

View 8 Replies View RelatedI've recently started coding in bash and I'm making a diagnostic check CD for rackmounted computers to print out to an LCD screen. So far it works but what i want it to do is, when it checks what ethernet ports are unplugged, it stays there for 30 minutes or so and proceeds through the script. I've looked up cron and that seems to be useful for making timers on permanent systems but I just want the cd to boot, do the check and then eject it and let the real OS take over and I've also tried using:
while [ `sleep 30m` ];
do
<script>
with no luck. Is there any command I can use to do this? I've noticed a few examples where people have captured the time and then used a while less than/greater than statement but I'm not sure how to do this. Is it possible to do a concept like:
while [ %current time -lt %current time+30 min ];
do
<script>

I'm trying to understand how interrupts work. Is there a way to generate timer interrupts in C. Also can we enter into the protected mode of the CPU. Does OS (specifically, linux) place any restrictions on user programs entering protected mode. If it does not, do we just have an assembly language program which changed the mode, followed by the C code... I'm just trying to understand how things work at the lowest level. So I'm trying to write few snippets to test my understanding.

I'm the official timer.If it counts up like in soccer rather than down, that's fine too. If the app can also show the score, that would be great, but it is not a requirement. We don't use a shot clock, so that is not required either.

My system: Ubuntu 2.6.31. Language C, compiler: gcc I am running dynamic timer as a kernel module and my issue is that the once the timer overflows, the program finishes. On the other hand i have forced to arm the timer again because of a while loop but the timer never is started again. i am targetting a periodic timer but it runs once and thats it.

I'm implementing a TCP protocol. TCP implementation requires to send packets continuously and if the receiver doesnt respond after a particular interval of time it should resend the packet again. I need some method to implement a timer expiry function. How can I implement it? Should i implement threads (If yes can you please give a sample)? or is there any better method? I'm implementing it in a Unix system.
