2563.0. "MIDI and Adaptec SCSI Controller...?" by RISIKO::GENIUS (I'm *not* this mouse!) Tue Jan 29 1991 05:19

For a few days I now own a SCSI disk with Adaptec controller. Everything
works fine except one: the SCSI Controller is using the same I/O address
as my MIDI interface (330H). Since the Midi interface has no option for
choosing the I/O address I changed the address of the SCSI controller to
something else but then the SCSI Bios didn't find the controller anymore.
Seems that it is hardcoded to 330H. Some solutions I could think of:

1. Stop playing music through MIDI
2. Downgrade from SCSI to RLL (... does anyone want a SCSI
   drive/controller...? :=) )
3. Buy a second computer for MIDI and build up a LAN for data exchange
4. Modify the MIDI hardware and path ALL the software for another port
5. Patch the SCSI Bios to accept an address other than 330H
6. Stop computing at all

Does anyone have another idea? Any help greatly appreciated!

2563.1Go for it!TLE::TLET8::ASHFORTHThe Lord is my lightTue Jan 29 1991 07:567
Well, uh, gee, Monty, I think I'm going to go for number 5!

I don't own an I-word PC, but patching a hard-coded address seems like it should
be relatively straightforward and get you out of the woods.

Cheers,

2563.2well...LNGBCH::STEWARTPlan to be more spontaneous!Tue Jan 29 1991 11:4725
1. Stop playing music through MIDI

	Non sequitur - does not compute.

2. Downgrade from SCSI to RLL (... does anyone want a SCSI
   drive/controller...? :=) )

	Acceptable in extreme circumstances - your choice.

3. Buy a second computer for MIDI and build up a LAN for data exchange

	Recommended option - I made the same choice due to slot scarcity.

4. Modify the MIDI hardware and path ALL the software for another port

	Fallback option - Least expensive.

5. Patch the SCSI Bios to accept an address other than 330H

	Got sources, a PROM burner, & time?

6. Stop computing at all

	Right...
2563.3There may be, or maybe not!VIA::CARROLLMon Apr 22 1991 20:5717
    There are some possiblites. I'm in the same situation (But I usually
    use my Mac II for music, or my Amiga, so I'n not stuck). MOst software
    nowadays will let you change the i/o address to something else (and
    mosy Midi interfaces). The only popular sequencers that cant so far
    are Texture and prism. Cakewalk will let you use a different address
    if you can change your interface to something else (usually 300). I
    think Sequencer Plus will too. I called Adaptec awhile back, and there 
    is a way to make your SCSI card thinks it at a different address, but
    its not ideal. You can buy something from them (I fogot what) and then
    remove your BIOS from the SCSI card, and then... get this... boot
    from a floppy!!! I got the musicquest midi interface 16S and it can be
    switched, but my favorite PC sequencer Texture doesnt find it. After
    calling Steve Rossi at magnetic music, he said, hummmm. They may do
    something in their next update. Until they do, I'm happily back 
    sequencing with my Mac and maybe some day I'll get to play with
    Texture again....
