My XT clone has 2 x 256K and 2 x 64K memory banks. Could I replace the 64K chips with 256K chips and some how make use of the memory above 640K? Such as with programs that can access "Above Board" memory. Paul Baldock p.s. please reply directly (and to the net)

Hi, I have recently got my first IBM computer. For some reason, I have one meg of RAM and I am not able to utilize the extra 384k worth. I understand that there are programs out there that would allow me to use the extra RAM. So anyways, can someone tell me if there is a good pd or freeware program out there that I can use? If so, where can I get a copy of it? I would really appreciate it if you would send me a copy of it because I cannot FTP. Thanks in advance, Wayne wngai@paris.ics.uci.edu

If you have a 8088, and the extra 384K RAM is not EMS or EEMS memory, then that memory is unusable. If you have a 286 and the extra 384K is not used for shadow ram and is accessable, it can be used as extended memory. Disk caches, ram disks, and printer spoolers usually use extended memory for holding data. If it is not accessable or is used for shadow ram, it is not accessable. It can also be converted into EMA memory to used by a program that supports EMS memory. If you have a 286 and the extra 384K RAM is (or can be) set up as EMS or EEMS memory, then you can use it with programs that support them, or buy a program such as QRAM by Quarterdeck to turn it into high memory which can be used to load drivers other small ram resident programs. If you have a 386, and the extra 384K is not used for shadow ram and is accessable, it can be converted to EMS memory and/or it can be used as high RAM. But if the extra memory is not accessable or used for shadow ram, then that can't be done. The extra 384K RAM can be converted by QEMM-386, 386-to-the-Max, or equivalent. I'm sure I must have missed a point or two, but this in general is how it goes. ------------------------------------------------------------------------------ | Sam Shim | "I am a computer consultant. | | EECS Departmental Computing Organization | I deal with User IQ errors!" | | University of Michigan | "It's not a bug, it's a feature!" | | internet: shim@eecs.umich.edu | "A mind is a terrible thing." | ------------------------------------------------------------------------------ "Love is a shield to hide behind" - Camouflage
