Hi all,

I've just built a OSR5.0.5 clone pc and it will not pause at the Boot:
prompt no matter what timeout setting I put in /etc/default/boot. However,
if I change the AUTOBOOT parameter to NO it will pause at the Boot: prompt.

This is a copy of /etc/default/boot that will not pause:-

DEFBOOTSTR=hd(40)unix swap=hd(41) dump=hd(41) root=hd(42)
AUTOBOOT=YES
FSCKFIX=YES
MULTIUSER=YES
PANICBOOT=NO
MAPKEY=YES
SERIAL8=NO
SLEEPTIME=0
BOOTMNT=RO
TIMEOUT=15

Can anyone offer me any suggestions as what might be causing this problem?

Greg

Buggy BIOS?

/boot's timeout is done by calling a BIOS function repeatedly to ask for
10-millisecond delays (checking the keyboard between delays). The BIOS
function is INT 15h, AH = 86h, with CX:DX == 10000 decimal. (See
http://www.ctyme.com/intr/rb-1525.htm).

Another possibility: make sure that /stand/etc/default/boot has the
timeout setting in it. That's the actual file read by /boot. Normally
/etc/default/boot is copied there during a shutdown, but there are ways
that can fail.

Hi

I dont know why it doesn't wait, but i know there was a bug in sco 505
which made the made the boot hang for ~30 secs at boot prompt. This
was solved in rs505a. perhaps this solves your problem too. By the
way. The bug was a result of using init 0 instead of the correct
shutdown command

Bela,

Thanks for your reply, I was thinking it was the bios too but did not have
the info. that you did.

Thanks again,
Greg
