Hello everyone, I have an older system (DEC PC XL 590) into which I have installed an ISA serial port expansion card from Digital Research Technologies. The motherboard is too old to be PnP; PCI irqs are set in the BIOS, but there does not appear to be an equivalent option for the ISA slots. The card is jumper configured to operate on IRQ 5 and 9 as GENERIC indicates is typical for COM3 and COM4. The kernel was rebuilt and devices made as instructed in the Handbook (I've built lots of kernels but have to create devices less often). The ports do not work. dmesg reports: sio2: configured irq 5 not in bitmap of probed irqs 0 sio3: configured irq 9 not in bitmap of probed irqs 0 I read some of the related source code (src/isa/sio.c) but have not uncovered any clues about how I might get FreeBSD to probe those irqs. Can someone help me? Regards, David Drum david@mu.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
