[comp.unix.i386] Intel spec 32-bit slots

ken@gatech.edu (Ken Seefried III) (08/11/89)

---

I require some information concerning the Intel 32-bit bus.

First, where does one find the specification for this bus?

Second, I would like to know what machines provide an Intel slot.
Obviously, those machines with the Intel motherboard do, as do those
using the Mylex MX series board, but who is that?

Lastly, I am curious as to what boards have been designed to use this
board, especially memory boards larger than 2MB.  So far, I know of
the Intel 2 MB RAM boards and the Mylex MX376 SCSI controller board.

The Intel OEM manual for the "301" motherboard contains information
on the 301-style 32-bit bus. The "302" manual has similar information
for the 302-style 32-bit bus. You can't take 301 memory cards and
put them in the 302.

The only cards I know of are the Intel 2 MB dRAM card, the Intel 8 MB
dRAM card, and the SCSI controller board you mentioned.

I have an Intel 302 box, and the manual says that the spec for the 32 bit
slots is Intel proprietary, see your Intel salesman and beg.  Thanks a lot.
I would be interested in hearing about reasonably priced sources for the
memory cards; I suspect that 8MB won't be enough once I load up NFS and
X windows.

Whoops, there may be different manuals depending on where/how you get
your box. I dunno...

As for memory, having worked quite a bit with a configuration similar to
what it sounds like you are setting up, 8MB is probably enough. Once you
get set up, you might try using "sar" to analyze your memory usage. Of
course, the more X clients you run, the more memory you'll need. Plus
the kernel gets bigger and bigger. With X, TCP/IP, NFS, Tape driver,
RFS, and so on, the size(1) total of the kernel will exceed 1.6 megs.
(your mileage will vary). More memory never hurt anyone to my knowledge :-).

As for second sources of Intel memory cards (I assume that's what you mean
by reasonably priced sources) I have seen ads in the back of computer rags
selling "Intel motherboard-compatible memory cards" for less, but not *much*
less, than Intel sells them for. Sorry, can't recall any company names, and
I haven't seen any such ads in the last couple months.

Good luck with the search.
