I have one of those early 7300's with only 1/2 a meg. on the mother board. I also have a 1/2 a meg. on a ram card. After putting one of the combo cards and populating all of the empty sockets which is supposed one and a half meg's worth of space, the 7300 reports only 2 meg even though to my calculations it should report 2.5 meg. Is there anyway I can fix it? or am I a victim of an early version of the machine? Reza Zarafshar 312-979-5104 ihnp4!ihreza!reza0

In article <1396@ihlpl.UUCP> reza0@ihlpl.UUCP (H. Reza Zarafshar) wants to
know why he has 1/2 MB on the motherboard, 1/2 MB on a RAM card, and 1 1/2
MB on a combo card and his unix pc only sees 2 MB.
To the best of my knowledge, and contrary to what the manual says, you can
only put one memory expansion card on a unix pc and have the system see it.
The problem is not hardware, so I suppose that there is some hope that this
limit might change in future, but personally I am not holding my breath.

I am writing this on a 7300 with .5MB on the motherboard and two .5MB RAM cards. It has worked under R2.0, 3.0, and 3.5 of UNIX. Harvey S. Cohen, mtuxo!hsc

When I ordered it, I asked for 1 meg, so they sent me an additional 1/2 meg card. This works fine. Later, I got a combo RAM/EIA board, with another 1/2 meg. I installed this and the system DOES see 1 1/2 meg total. Perhaps there is something strange about the combo board as compared to a regular RAM board... On the other hand, perhaps there is some upper limit on the amount of RAM on expansion boards. -- Harold Bamford AT&T Bell Labs IE 2F-524 (312) 369-7397

I recently upgraded the memory on a PC7300 here. It started with 1/2mb
on the motherboard and 1/2mb on an add-on card. We bought a 2mb add-on
card, and it turned out that the 1/2mb card has to be removed first.
The configuration guide that comes with the 2mb card gives the various
possible configurations, and you cannot have any other RAM cards with
it. Therefore, the maximum memory you can have is 2mb plus whatever is
on your motherboard, which gives us 2.5mb.

Jonathan Clark [NAC,attmail]!mtune!jhc You can get the combo board and .5M board both to be recongised. It makes a diffrence which slots the bords are put in. If you look in the appendix of the installation guide it tells where to put them. (NOTE they number the slots diffrently then other people.) -jim colsmith -- J. S.
