Compaq OEM BIOS + Reboot linux

Hi,
I installed Linux (Redhat 7.0 ) + Kernel 2.4.19 on a Compaq Deskpro DP6000 (6266MMX).
All is working well, but i have a trouble with warm boot (same as this url :
http://mail-index.netbsd.org/port-i386/2002/11/25/0012.html
)
I installed the latest version of lilo (but I don't think lilo is concerned).
I didn't find any fix about this trouble.
I tried to see kernel sources, and I'm quite sure that the BIOS call for reboot had something wrong. As it is binary datas, I don't know how to debug it !!
If someone knows a little about this Compaq BIOS (Compaq is now HP ???) , it would be helpfull.
regards

Re: Compaq OEM BIOS + Reboot linux

Hi.

Did you try passing reboot= kernel option ?

Available choices are :

warm
cold
bios
hard
smp

So reboot=warm etc.

Re: Compaq OEM BIOS + Reboot linux

From the source code :

#ifdef CONFIG_SMP
case 's': /* "smp" reboot by executing reset on BSP or other CPU*/

Re: Compaq OEM BIOS + Reboot linux

Hi,

Just my two pennies:-

I've seen this happen with compaq laptops in particular, and its usually something to do with the power saving options in the bios. Either try and disable the power-save functions or obtain the kernel patch for ACPI, which sometime s solves the problem...

Cheers,

Re: Compaq OEM BIOS + Reboot linux

hi,
Well, reboot=smp didn't change anything. Power save is already disabled...
I will look for if there's something into the kernel with APCI... May take some times ! I will try to enable the power save and add the apci functionnality ?
If someone has any other idea ??

thanks

Hello again,

Hmmm. Try using the reboot=bios and noapic options at boot time, with all apic bios features turned off.


Hope it works!

Re: Compaq OEM BIOS + Reboot linux

Hi,


Another thought..... I've seen various people on the web complain about this issue, most of them say it can be resolved by using one of the older 2.2 kernels - maybe worth a try also!!

Cheers,

Re: Compaq OEM BIOS + Reboot linux

Hi,
I tried both without any more successes.
I could not got back to 2.2 kernel (I'm using some feature which exists only in 2.4).
But I will try to see if reboot can work with another kernel, and if it works, then I know there's a solution .
thanks for your help.
