Toshiba has a "resources" document on the 8000 with the following table: IRQ Use Notes 0 Timer 1 Keyboard 2 PIC #2 3 Modem COM port, modem 4 COM COM port, modem 5 Sound system COM port, printer, modem, ECP, MPU* 6 3.5-inch diskette drive 7 LPT1 COM port, modem, ECP, sound system, or MPU* 8 Real-time clock 9 Not Available Reserved for system 10 Available COM port, sound system, MPU, modem 11 External PCI bus Modem, sound system, FIR, or MPU* 12 PS/2 mouse 13 Math coprocessor 14 Hard disk CD-ROM, secondary hard disk 15 CD-ROM CD-ROM, SelectBay The other thing that affects this, at least in terms of FreeBSD and PC Card use, is the BIOS setting for the card slots. If the "Configuration" is set to Setup by OS (PNP, I think), and PC Card "Controller Mode" is set to Auto-Selected, multiple cards seem to be happy with sharing irq 11. And that's what they get, regardless of what is specified as available in /etc/pccard.conf. If PNP is disabled and the PC Card controller is set to PCIC Compatible, then the cards each seem to need a separate irq. (This is how I had been trying to run it.) -Warren Block * Rapid City, South Dakota USA To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
