I am planning to install 16Mb of RAM on a 386 motherboard that actually has a Computone AT8 intelligent serial card installed, addressed in the range of 15MB. I run ISC 2.2 on the box, and would like to know if someone out there has managed to get 16Mb running and co-existing with Computone on the board. Rick

I am running a 3-high-speed-lines BBS and on the same box I do heavily X development. My 8 Mb are no longer enough to get satisfactory performance (I still have a 20 MHz board :-() so I would like to add some memory, up to 16 MB. It seems not possible to get a Computone board work if you have 16 Meg on the board (even if I have not tried it yet, just asked around) and I cannot map the card below 1 Meg because all the available space is occupied by my 1-meg VGA card, the hd controller bios, the tape streamer bios. (This makes also me wonder where the 1-meg VGA video memory is mapped... any clues?) So it seems that I only can go up to 12 Meg on the board. I read somewhere that you have a multiport board too -- how much memory do you have on your box?(and also what kind/brand of motherboard you have?)

Motherboard is a unknown - 33 mhz 386 that holds 12 megs of SIMMS and 4 megs of DRAM - for a total of 16 megs. Right now I have 12 megs full - and would like 16 megs - but I honestly believe that I won't be able to address the additional memory. Prior to this motherboard, I tried another (it only supported 8 megs of RAM) - and this one appears to be 5-7% faster. Computone's drivers are being rewritten by a third party - so hopefully they will work sometime in the near future at an address below 1 MEG. If so, then I should have no problems installing another 4 megs in this machine. Are you running X11R3 or R4? R4 is leaner on system resources - and from information I've gathered is much faster handling video IO. -- Larry Snyder, NSTAR Public Access Unix 219-289-0282 (HST/PEP/V.32/v.42bis) regional UUCP mapping coordinator {larry@nstar.rn.com, ..!uunet!nstar!larry, larry%nstar@iuvax.cs.indiana.edu}

R4 is leaner on system resources - and >from information I've gathered is much faster handling video IO. I know that, I am developing with X since about 16 months. At home I run the excellent Roell's server, and it is really fast when I am the only user on the box, but becomes a little slow if there are two or three more users logged in. Pretty normal I think, with a 20 MHz 386.

My 8 Mb are no longer enough to get satisfactory performance I encountered this when I went to networking and X and hit a hard stop at 12Mb. Everything was just fine when I only had 8Mb but I was not able to find any address where the AT-8 would work with 12Mb installed. Mine is a 33MHz caching Micronics and I did disable the cache in the Eth megabyte and the Computone card worked well addressed in the Eth megabyte. When I went to 12Mb (which stops in the Bth megabyte) there was no address anywhere that the Computone would live at and function. I could disable caching and have it work OK but that defeated the purpose. Ditto with an AMI motherboard, and that one only has 4Mb! It seems that different caching schemes and large amounts of memory are more than the Computone hardware can handle. The symptom I observed was that the device driver came up and claimed that the board was not there. Just to verify that I hadn't done something stupid, I went back to 8Mb and it worked, disabled the cache and it worked, went back to 12mb with the cache still disabled and it didn't work. This is going to sound like a thermonuclear fly swatter, but what I did was to put another machine on modem (and printer) duty and networked to it. This had two side benefits. I was eligible to relax the security on ssbn since people I don't know no longer had roaming privileges and their response time improved considerably since they weren't competing for cycles with my X development. You might find that a "throw away" box is a viable solution with some additional benefits. It's a pleasure to be able to break ssbn or take it down (gasp! to boot native DOS) and not get a lot of howling from the dial up users. -- Bill Kennedy usenet {att,cs.utexas.edu,pyramid!daver}!ssbn.wlk.com!bill internet bill@ssbn.WLK.COM or attmail!ssbn!bill
