configuring 5.1b2 for isa-ide laptopsRe: 5.1b2, configuring kernel for Thinkpad x20

[john at utzweb.net]

Hi;

I have a laptop HP Omnibook 800CT that runs 4.X rock solid, but i have
been unable to get 5.X to install on it because it cant find the hard
drive.

This laptop is very small, old and kinda weird in some parts (for
instance, it has a scsi port for the CD!), but, as i said, it runs 4.X
just great.

Matter of fact, the *only* reason that i have for switching to 5.X is
cardbus, but that's reason enuf.

I believe the wierdness in this platform centers around it's highly
integrated ( by 1997 standards ) chipset, manufactured by VLSI. I cant
find any documentation on this thing anywhere other than the PnP ID
Numbers.

After reviewing this thread, it's left me wondering if my problem is that
5.0 expects the IDE controller to be on the PCI bus and my goofy chipset
has the IDE controller on the ISA bus.

So, my question:

is there a sysctl that forces the kernel to look on the isa bus for the
ide controller?

or is there a sysctl that forces the kernel to look for the ide controller
in a 4.X-ish way :-)

tnx!
