All I can tell you is that the Adaptec 1542b kit does not. We recently bought
an Adaptec card under the illusion that we would be able to write our own
device drivers, disk maintenance utilities, backup utilities etc.

When we asked for a tech manual to give us the register level info needed,
we were told that this information was proprietory ! Any drivers etc. must
be purchased from adaptec. This is NOT the type of support we are used to
getting to say the least.

If anyone knows of a vendor that supplies high performance SCSI host
adaptors, and also includes programming info please let me know !!
