this seems really poor bios design: @mini rminnich]# lspci -v -v | grep Interrupt Interrupt: pin A routed to IRQ 11 Interrupt: pin B routed to IRQ 11 Interrupt: pin C routed to IRQ 11 Interrupt: pin A routed to IRQ 11 Interrupt: pin B routed to IRQ 11 Interrupt: pin B routed to IRQ 11 Interrupt: pin B routed to IRQ 11 Interrupt: pin A routed to IRQ 11 Interrupt: pin A routed to IRQ 11 Interrupt: pin B routed to IRQ 11 Interrupt: pin A routed to IRQ 11 Interrupt: pin A routed to IRQ 11
Pretty much everyone goes to IRQ 11.
And a bunch of Interrupts go unused:
CPU0 0: 3381694 XT-PIC timer 1: 13873 XT-PIC keyboard 2: 0 XT-PIC cascade 8: 1 XT-PIC rtc 11: 77842 XT-PIC usb-uhci, usb-uhci, usb-uhci, eth0, wlan0, Ricoh Co Ltd RL5c476 II, Ricoh Co Ltd RL5c476 II (#2) 12: 360259 XT-PIC PS/2 Mouse 14: 85559 XT-PIC ide0 NMI: 0 ERR: 0
Is there any reason a BIOS would do this?

The motherboard is a lousy design. Only vary rarely have I not seen the basic irq assignments come down to traces on the motherboard.

what's worse is the PIR table claims that lots more interrupts are available. Sad, really.

You wish! This is on my R31 lspci -v -v|grep Interrupt Interrupt: pin A routed to IRQ 11 Interrupt: pin A routed to IRQ 11 Interrupt: pin B routed to IRQ 11 Interrupt: pin C routed to IRQ 11 Interrupt: pin A routed to IRQ 11 Interrupt: pin B routed to IRQ 11 Interrupt: pin B routed to IRQ 11 Interrupt: pin B routed to IRQ 11 Interrupt: pin A routed to IRQ 11 Interrupt: pin A routed to IRQ 11

and attached that of my girlfriends r32 BTW Ron, if you (by chance) figure out the base address of the i2c bus in the X24 please mail me, I'm trying to get s-video out working with my graphics chip (i830) and need both the i2c and i830 base address for that (must be in the range of 0x05014) Cheers Robos
