Jack,
Thank you once again for your SCSI elucidation.
It's very reassuring to know that the ASPI drivers (one for each type of SCSI
device on the chain) reside mostly in extended memory. How about the ASPI
manager itself?
So I guess if you want a really fast SCSI hard disk, then you go with the kind
that has BIOS on the adapter. Does this then take up some memory at C800:0 or
something? Also, it sounds like these cards, in addition to supporting two
hard drives and two floppies, also will support a chain of 7 SCSI devices?
Finally, you said that SCSI hard drives have their own cache. This can't be
very large, I don't suppose — certainly not megabytes, right? I know you can
get ISA or EISA controllers with large amounts of memory (4-16 meg), and it
supposedly helps disk throughput. What is the equivalent SCSI setup?
Thanks again!
