- I cannot tell you how strongly I recommend against doing that other than to say
- that six months after you start trying to make it stable and effective and fast
- you will probably suicide unless you are in the Ralph Babel levels of
- programming abilities or above.
-
- 1) You need board schematics.
-
- 2) You need documentation for all the major parts on the board.
-
- 3) You need the complete Autodocs and Includes files.
-
- 4) You need to carefully read and fully understand the SCSI-2 specification
- *AND* its implications for the devices you wish to control.
-
- While the latter two are easily available and the second is fairly easy to get
- from parts manufacturers the first one will take you considerable effort to
- reverse engineer the board AND the programmable devices on it. Since this is
- what makes the board what it is you can almost take it to the bank that GVP or
- its successors will not release that information lightly.
-
- What is it you want to do? (If it is SCSI IO with the OS disabled I'd recommend
- kissing it off.)
