RE: Kernel for linuxbios

[Dave Aubin]

Two things strike me as odd.

1.  Your ," PCI: IRQ 0 for device 0000:02:00.1 doesn't match PIRQ mask -
try
pci=usepirqmaskPCI: 02:01.0 [1022/7462] disabled"
   Type of errors.  Looks like you pcirqp map is bad?  Are you making
your
Own mother board?  If so it is important that you get this and the mp
Table correct based on your wiring.

2.  You did get to initramfs, good job, but it did fail to mount you
File system.  This could be anything.  Please send your init script
And Describe what are you trying to mount.  A USB stick, ide, what?

I took your advise and try the 2.6.
I am using the initramfs_data.cpio.gz from the link you send me.

The mkelf command is:

./objdir/sbin/mkelfImage -t bzImage-i386
--kernel=/home/sagivy/bzImage-2.6. 	--command-line="rw
console=ttyS0,115200 root=/dev/ram0"
    --initrd=/home/sagivy/initramfs_data.cpio.gz 
    --output=/home/sagivy/bzImage2.6.8.elf

And here is the output:

Sorry for the late response.  Are you using Linux 2.6.*.  If so give
initramfs a try.
Here is a link to aid you in how:

I tried to use initrd - same problem.

use initrd, not ramdisk!
