- Whenever I try and run my bus speed at anything higher than 8Mhz
- everything works fine except my hard drive. I have a combined floppy/hard
- controller, but it ignores the hard drive and asks for a floppy in a: to
- boot from. Anyone know why that would be. The drive is an ST251-1 and gets
- about 28ms at best. Could this be the problem that data is not reaching the
- controller as fast as the bus wants it?
