We're talking about different things. I'm talking about the ISA transfer
rate, where I have yet to see a main board which will work reliably with
a setting faster than 5.7M/second. Sync. transfer speed would be the
data clock between the drive and the host adapter. You're still limited
by what you can get accross the ISA bus.
