I have one of those nearly useless AmiBIOSes in a Pentium2 box. It does nothing for ISA-PnP cards except to print their names. I have forced it to assign the same IRQ to all PCI cards or I would not have any left for ISA cards, ISA-PnP or not. Considering that 1) there are only a few valid SB8 ports, and 2) a wrong port is detected immediately, and 3) there are only three valid DMA channels I think an IRQ auto-probe is the most useful one of the three. You'd need an average of 15 attempts to guess IRQ and DMA at the same time (10 possible IRQs, 3 possible DMAs). AFAIK, autoprobing for IRQ works well in practice. > By the way -- are you in fact using a SG NX Pro? Not a SG NX Pro 16 or > some other 16-bit SG? The NX Pro should have an FCCID of I38-MMSD802.

According to , all of I38-SGNXPRO, I38-MMSN802 and I38-MMSD802 are SG NX Pro. The three largest chips on the board are AZT-NXPMIX0592, AZTSSPT0592-U01 and AZTDSP31H. There is room for a SCSI controller chip and a SCSI connector. There is a Mitsumi CDROM interface. -- Rask Ingemann Lambertsen ------------------------------------------------------------------------- Take Surveys. Earn Cash.
