Compaq Deskpro EN PII 350 hangs after reboot command, while trying to
re-initialize bios. Have to power off then turn it back on (no reset
button) to restart.
Comment 1 Bailey, Greg 2000-09-26 14:33:07 EDT
I've observed the same behavior on a Compaq Professional Workstation SP700
Comment 2 Alan Cox 2000-09-30 22:19:46 EDT
You can change the reboot method but really its up to the BIOS to restart
correctly from a hard
reset as Linux does.

There are several options for rebooting a PC. Linux defaults to a cold reboot
via reset

w - warm reboot
c - cold reboot (default)

and the methods

b - bios reboot
h - hard reboot (default)

You can set these on the boot comand line by eg

Lilo: linux reboot=b,c     (for a cold bios reboot)

If that works then you can use append= in lilo.conf to set it by default

Fundamentally though I dont think its a Linux problem, let me know if the b,c
cures it on these
compaqs though.

I have the same problem on an AP400, and
no combination of warm/cold, biod/hard fixes it.

None of the previous comments seem to mention that in
6.2 (for example), there is no problem with rebooting.
Does rh7.0 do something different from rh6.2?
Comment 4 Pieter Krul 2000-10-06 13:03:58 EDT
I'm experiencing the same sort of problem with a Compaq Deskpro 4000
P5 233, 128MB memory, standard RH 7.0.
On a warm reboot, booting gets stuck on lilo's `L', same with reboot=b,c
in lilo.conf
Hard reboots work fine.

There's no diagnostics partition anymore on this machine, and Linux boots of
a SCSI disk attached to an Adaptec PCI SCSI card.

alan,

i have the same problen on my presario 4508 duel boot with nt, i have a 12 meg
fat, then installed nt, by default the nt loader and noot.ini will be installed
on the fat partition, i then upgraded from 6.1 to 7.0 and the system will not
reboot, i have to shutdown then turn off/on the system to boot, yes lilo is
installed in the mbr, forgive me if i seam to be a novice but what must the boot
line look like in lilo.conf to add the b,c parameter, i assume after i edit
lilo.cong i can just run /sbin/lilo to update lilo.cong, here is my current
lilo.conf.

boot = /dev/hda
timeout = 50
compact
linear
prompt
   message = /boot/message
   default = linux
   vga = normal
   read-only
map=/boot/map
install=/boot/boot.b
image = /boot/vmlinuz-2.2.16-22
   label = linux
   root = /dev/hda7
other = /dev/hda1
   label = dos

thanx
kjt

The problem is still in RH7.1
Comment 7 Need Real Name 2001-08-24 20:25:45 EDT
Apologies, but I think I've duplicated this bug in bugzilla report # 52367. 
Please check 52367 for more details regarding this bug.

Comment 9 Luca 'FISH' PERSICO 2004-06-21 16:39:02 EDT
Hello there!

I had a similar problem on a Clevo 2700S laptop. I simply solved it
putting the option:
reboot=bios
among the arguments of the kernel line in grub.conf.

Many thanks to everybody.
