Robert,
I hope you will read this just in time: using the 2090A with RDBs (rigid
disk blocks) is not direct possible! You should have got an install-disk
with "prep"-software; it will install a small boot-partition with the size
of 2 (two) tracks, which is unfortunately not compatible with HDToolbox.
If you don't want to boot from the hd-drive, you are more lucky:
Find out the number of heads (probably 4), sector-number (probably 17),
and possible tracks (about 612 to 615); then you must write a "mountlist"
and mount your HD with the mount-command.
I hope you are familiar with the interna of your A2000; if you need help,
just give me the name of the HD-manufacturer, the type of the HD, and I
can write the mountlist for you. This is not much work for me, because I
also own an old 2090A-board and feel with you.
By the way, if the HD is an MFM-type and the manufacturer is EPSON, you
should not use it together with any turbo! It's too slow, and you will
often win a trip to india then. And the biggest SCSI-drive (drive, not
partition) you can use is 270MB. Don't try a bigger one.
Hope it helps… — Harry with AP from Germany
