[ale] Need Info: "Ten Time" (SST?) SCSI Controller

[John M. Mills]

Venard -- Thanks.  I'm making a little headway.  For starters I printed
out the beeegggish SCSI-HOWTO.  Now my desk stays nicely in place.
I reply in case others are tracking this:

V I think that ROMADDR is what address the device would ike to think it is
V located at. Common ones for some devics are 0x300 and such.

I think this is actually the function of the I/O ADDRESS jumpers, containing
bits 4-10, and currently jumpered to [maybe] 0x4B0

I think ROMADDR is the BIOS entry commonly, bits 14-19, and commonly set at
something like 0xD8000 (0xA4000 at present, if I read right.)

V You have to
V make sure that it doesn't conflict with your ethernet cards, cd-roms and
V such

Understood.

V The 50 pin cable is the internal scsi connector for internal scsi devices.
V The 34 pin connector is likely a floppy controller just like the one that
V you have on your IDE controller card or your motherboard.

Understood -- jumpers for FD are more or less self-explanatoru.
