Hi There!

I have a dual pentium II computer, with linux 6.2e with a dual
processor.
I need to convert my actual kernel: 2.2.14-11.ifssmp on a 2 processor
i686 computer toa single processor, I got one of those ide raid
cards, and this thing won't work on a dual processor computer, does
anybody know how to do this?

Any help would be appreciate it.

Joseph

Interesting... I have a dual proc box at home, and a Promise raid card.
Everything works just fine. Give some more info and I'm sure someone will
have an anwser for you.

Have you tried adding "nosmp" to your kernel parameters? With LILO you
can manually do "image-name nosmp". To make it permanent, add it to the
appropriate "append=" section of lilo.conf and re-run lilo.

Ok, the complete profile is as is follows:

Dual pentium II, Linux 6.2 e, running a kernel version: Kernel
2.2.14-11.ifssmp on a 2 processor i686

The IDE card is a dual channel ata133 raid adapter RocketRAID 133 from
highpoint, the instruction say that this device wont work with dual
processors, so the computer is booting with the normal ide way, two
drives 30 gb each, when conncetde to the card I unplugged the ide
cable, connect the harddrives to the ide card and I change the bios
section to none hard drives, the bios recognizes the card and boots
ok, the card recognizes the hard drives ok, Linux starts to boot up,
but when mounting root, I get this message:
"VFS: unable to mount root fs on 03:06"

on the linux side, I reconfigure the kernel with support for ide
cards, the dual processor support is "n", I recompile the kernel, but
when I boot up I have the same problem, so I don't know how to kill
the dual processor and make a uniprocessor kernel.
Again any hints would be appreciate it.

That's a very old kernel. You may need to consider
upgrading.

I see no indication that it's a problem due to the use of
dual processors. It seems like your old 2.2.14 kernel
doesn't recognize the new HighPoint controller. It's
looking for, but not finding, your boot partition.

Try a newer kernel. Perhaps somebody else out there can
reccomend which ones support booting from the HighPoint
controller. 2.4.18 claims support for some HighPoint cards
(maybe this one, maybe not) but doesn't mention any problems
with dual processors.

What makes you think that your problems are SMP-related?
And are sure you really want to let your second CPU go to
waste to use this card? Wouldn't software RAID make a lot
more sense?
