I know nothing about SCSI controllers, but believe some have a BIOS, but most are used by communicating through . The objective of my question is to figure out if I can make my Ultra 10 less PC-like by putting in a PCI IDE-RAID acting like a SCSI-card. I don't want to buy it and get bad surprises, though :-) If SCSI is supported, and an IDE-RAID card presents a SCSI interface to the driver, shouldn't it work? The only thing I can imagine that woudl keep it from working, would be if the driver needed some functions that could not be emulated by the card, but what on earth would they be? To someone building a driver for a PCI card, PCI is PCI OpenBoot or not, right? If a driver for an IDE RAID could be made, I think many U10 owners would be happy, there is no doubt to me that the IDE is what makes the U10 PC-like ... Here are some specific questions that might help me understand in case it is impossible or impractical to put a non-Sun SCSI or IDE-RAID card in the U10: What is at 0xC8000? If it needs to be remapped, is there no place in the U10 address space it could go? Does the U10's CPU need to be able to run any of the SCSI-card's BIOS code? Isn't worst case scenario one where I would make use of my EPROM burner and replace the BIOS on a PC RAID-card with SPARC instructions? BSD doesn't require OpenBoot-compatible PCI cards, does it?
