I flashed my Bios with 030811. There were no operation problems prior to the upgrade. I was working on a LNB upgrade for a 250 Gig Hard Drive. Thought a bios upgrade might help in recognizing the big drive. I now have two problems: #1 - I can't boot my system with Processor/Memory set at 133/133. The system only gives me a black screen as monitor has yellow light. The CD and DVD drive lights flash back and forth. When I set the Processor/Memory down to 100/100, then I get a clean boot . . . except for problem #2. #2 - When I do use the 100/100 settings, I must have a boot CD in the CD drive for my system t continue the boot process. If I don't have a bootable CD in the drive, I get a Norvell error that asks for a boot floppy in the A-Drive to continue. I now have a big drive, but I can only run my machin at about AMD1200 speed (instead of 2000) with a boot CD in the CD drive everytime I boot up.
