The MultiPort Board SCSI device driver is now "SCSIdirect". What I need
now is a fairly complete list of all of the ANSI SCSI commands. If anyone
has a complete list, then please email it to me (or call RoboCity). I
have compiled a list from various tape drive and hard drive manuals, and
would like to include a nice header file with some source on how to access
the device driver. Any help appreciated.

I posted a few days ago to note that a friend had found a way to do SCSI direct on a 2090a. It seems that a bit that tells the dma chip whether it should read or write is never getting set, so the dern thing always thinks it's supposed to read. The work-around is to pull up bit 24 of the data buffer address (addr |= 0x1000000) in your SCSI direct packet when you write. Fortuitously, since the 2090a driver isn't setting this when it's supposed to it also leaves it alone:) The same code will work successfully with the 2091. The driver will overwrite the bit with it's own. The news I got today is that although the 2090 driver doesn't support SCSI direct, the 2090a driver, (when used with this method), works just fine with the 2090:) Patrick Horgan phorgan@cup.portal.com

Some time ago, I added the "SCSI Direct" protocol to my homemade SCSI system. The only documentation I had to go on was the include file "devices/scsidish.h". It seemed pretty understandable and my implementation works fine, but I am not sure if it is really done correctly. I wrote a simple program to test the implementation. This program allows you to interactively issue SCSI commands, transfer data into and out of a preallocated buffer, execute some "premade" commands, such as for formatting and parking disks, and so forth. I use it for all my disk maintenance. It would be nice if someone with knowledge of SCSI could try this out on a 2091 or a HardFrame. Also, if anyone has a simple program, which uses the SCSI direct protocol to perform some generic disk task, such as parking it, I'd like to try it out on my system. Could any interested volunteer(s) send mail to me at the address below? Thanks. Markus Wandel mwandel@tiger.waterloo.edu (519) 884-9547
