I didn't see these on a 440BX-based motherboard. I haven't seen that with my Gigabyte GA-7DX+ and 2940UW. There are some documented compatibility issues between the AMD-761 northbridge and VIA southbridge on these boards (see AMD's web site, though the symptoms don't sound all that similar), and there have been issues with VIA chipsets getting properly initialized by the BIOS. Maybe Gigabyte fixed the hardware between the GA-7DX and GA-7DX+, or maybe there is a BIOS update that fixes this problem. >> The only SCSI device I have in the box currently is a CD-RW, and >> I've never had errors on it. >> > > I couldn't reproduce the problem using the LEX board, so I went > with that. > > If this is harmless why write a bright warning to the console? > (Not to mension filling the log file). If I saw these errors, I'd be worried. Something that causes parity errors could also be corrupting data.
