In trying an install of the recent SNAP, I've run into a strange problem. System is an OPTI-based P90 with 3 VLB slots, 2 plain ISA (16bit) slots, and 4 PCI slots. I don't know the manufacturer. Has an award bios. VLB IDE controller, Genoa (Cirrus accelerated) VLB VGA, 2 Conner 1280mb IDE disks (which work fine and even configure and work in freebsd!!) The problem is that there is data/attribute confusion in the vga, but not under DOS at all. only_ under freebsd (but I haven't tried Windoze...) I could get through the install by knowing generally what was going on and hitting ^L a lot during the fdisk/disklabel steps. I presume that I need to fix some delay somewhere... Does anyone have a pointer to what? I've tried all the reasonable combinations of vlb and isa bus speed and wait state jumpers (this one isn't soft-config'd for these speeds) with no difference at all. I've left it at 8.33 mhz isa and '<=33' vlb with no vlb wait states (as the board came). We don't need the vlb performance (this will be a server anyhow and not run the X server) so will be substituting a cheap plain ISA vga card when we get it, just to save the vlb one for someone that needs it. I assume this will help, but don't know. However, has anyone seen this or something like it? Are there known limitations of this chip set? I could get chip numbers and date codes if needed... -- Pete
