| |
Hi all.
I have a system with an Abit AT7 motherboard: VIA KT333, single Athlon, 512M RAM, onboard RTL8139 network, USB, USB2, 1394. *NO* onboard PS/2 keyboard or mouse ports. Other: IDE HD, CD-RW, and DVD. Radeon 8500DV (will try getting that working later :)
I have used the system successfully with 2.4, and have been trying to get 2.5 to work. Until now, I haven't been able to get the USB keyboard to work. It is initialized by the BIOS, and is usable by GRUB for selecting boot images.
I finally found the culprit - "Local APIC Support on Uniprocessors" and "IO-APIC on uniprocessors". If both items are enabled, the network functions, but USB doesn't work. If not both are enabled (neither, or Local APIC but not IO-APIC), then the USB system works, but the network doesn't. :(
I am not using modules.
these are the only differences in .config:

Thanks - Steve
