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: multimedia linux-2.5.51 # diff -u working_network working_usbkeyboard_config3 --- working_network 2002-12-11 15:43:31.000000000 -0500 +++ working_usbkeyboard_config3 2002-12-11 15:15:53.000000000 -0500 @@ -63,9 +63,8 @@ # CONFIG_SMP is not set # CONFIG_PREEMPT is not set CONFIG_X86_UP_APIC=y -CONFIG_X86_UP_IOAPIC=y +# CONFIG_X86_UP_IOAPIC is not set CONFIG_X86_LOCAL_APIC=y -CONFIG_X86_IO_APIC=y CONFIG_X86_MCE=y CONFIG_X86_MCE_NONFATAL=y # CONFIG_X86_MCE_P4THERMAL is not set I can send complete configs, lspci / lsusb / whatever else anyone wants.
