The VIA chipset specs aren't available are they?

So who has KT266 chipset specs/info and can check/verify
that the expected IO APIC version is 0x02 ?

I think that it would be unusual.  Maybe they copied a
misprint from an Intel spec. but shouldn't have.

Hello,
I just booted 2.4.19SMP on non SMP P4, MB: MS-6533
(VIA). The console messages suggested me to write
to this email :)
I attached the log, see at boot at line 284. Also
lspci output is attached at end.

I should note that it remapped onboard RTL8139 ti
IRQ 18 and it doesn't work. When I compiled as
UP it ised 11 and worked well.

best regards,
