I am rebuilding my computer that uses an Abit NF7-S V2 mobo. This computer worked great until recently when the Promise Raid card died, causing an irreparable “fatal error” in the MBR of the XP operating system drive, so I am starting over with fresh drives. Here’s my problem: the bios on the mobo does not see my two SATA drives that are plugged into the onboard SATA plug-ins. It sees IDE drives just fine, but not SATA drives. When first booting up the two SATA drives do show up in the posting dialogue under Silicon Image RAID where it then states: “no valid device.”
But when I go into the bios, they are not there, and when I boot with the windows XP CD to install it, it soon hits a screen that says that there are no hard drives, confirming what I see in bios. I have tried a number of suggested bios settings that I have found in googling the problem, but I get the same result. I even installed a PCI serial ATA host card (Silicon Image sil 3114) and plugged them in on it and the same thing happens. I am at wit’s end trying to figure this one out. Any insights or experience with this mobo?
