Hi CD9000 and welcome to another M577 owner.
Hints and tips for flashing M577:
- use a clean boot diskette with no autoexec.bat or config.sys, if you can't make one because you have ME or XP go to
http://www.bootdisk.com
- make sure you can read the BIOS file from the diskette after copying it on, you don't want to find it's corrupt part way through.
- use Uniflash, available from Rainbow's site at
http://www.pppr.sk/rainbow/programs.html#UniFlash
- use the patched M577 BIOS at
http://wims.rainbow-software.org/ which is patched to allow the use of K6-2+/III+ with correct type speed display and disks up to 64 Gb.
I have K6-III/450 and IBM 40 Gb UDMA100 drive, using IBM Disk Feature Utility to set drive transfer rate to UDMA33.
