I've recently been okaying around with low cost motherboards and have been
problems on two of them: the BIOSTAT micro-ATX mobo M7VKQ, and the ESC L7SOM
mobos.
BOth work fine so long as I hold the kernel to 2.4.9 or earlier. Once the
2.4.10 patch is applied, the kernel no longer recognises the PCI Buss.
Under 2.4.9 /proc/pci shows:

HELP PLEASE! I don't want to be stuck on 2.4.9 forever!
I have one development box that I can do just about anything you wish to.
Please let me know how to help.
Thanks,

What happens on a modern kernel, 2.4.19 or 2.4.20-pre7?

2.4.20-pre7 fixes whatever the problem was. Kernels between 2.4.10 and
2.4.19 were broke for these mobo.
Did notice a new message: Using IRQ router SIS [1039/0008]
Thanks to whomever fixed it!
