Yes, many of the newer motherboards are using a chip by CMD known as the CMD PCI0640B, this chip look like 2 IDE controller, one at the standard I/O address of 0x1F0 and one at 0x170. This particular chip is ATAPI compliant, and does at least Mode 3 EIDE. > > > Award Pentium PCI BIOS and NCR PCI SCSI BIOS > > I see that we have the NCR SCSI BIOS, but there is no mention of NCR > SCSI support.

Almost all Pentium motherboards, with the Award bios atleast, are shipping with the NCR PCI SCSI BIOS built into the system bios. This means you can use the lower cost (ie ~$75.00) NCR 810/825 controllers that do not have any BIOS on them. If you do not have the NCR PCI SCSI BIOS in the SYSTEM bios you have to use an NCR card that has a BIOS chip on it (ie more $$$) or you have to boot from IDE and load run time NCR drivers from config.sys. My recommendation is don't buy a PCI motherboard without the NCR BIOS built into the motherboard, even most of the PCI/486 boards have it now too.. > Nate -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Custom computers for FreeBSD
