How difficult is it to directly program an ISA/EISA host
adapter? Ie. how good is the hardware-level documentation from
the various vendors?  For example, does the Adaptec SCSI Master
kit provide register-level documentation for those who want to
roll their own drivers (I know about ASPI but what about under
OS/2?)?  How about DPT, Mylex, etc.?  Target operating system
is initially DOS and OS/2 1.3, to be followed by Unix SVR4 and
OS/2 2.0.
