I actually really like the "Protected Mode Software Architecture", the "EISA", and the "ISA" books. The "Cardbus" and "Firewire" titles are also useful. Sorry to contradict you, but the "Plug and Play" is sufficient to let someone write "PnP OS" code, by manually scanning devices in the OS, instead of trusting the BIOS, which is good enough for me (I had an old box that had a built in bus mouse on IRQ 12 that wasn't in the BIOS; a PnP OS got this right; non-PnP OS's always failed to do the right thing, and reassigned IRQ 12 to a conflicting device (the second disk controller, on that particular box). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
