The current rumor is that it's only SCSI controllers, maybe adaptec,
maybe the device driver, that doesn't work right if the 486 runs at
33MHz.  I have not tested this configuration myself.

I know for fact that at least our SysVr4 works at 33MHz just fine with
ESDI - I run my work machine at that speed most of the time.
