I have upgraded my work computer from an IBM XT to a WIN TurboAT, and ordered the new machine with 1 meg of extended memory on the theory that this would help me work with large graphics files (Zsoft Publisher's Paintbrush). The problem came when I discovered that the drivers for the extended memory seem to be taking up some of the original 640K, to the point that programs like Ventura Desktop Publishing (which requires 512K free) would not run. I eventually tweaked the switches on the drivers so that I could run both Ventura and the extended memory. Now, however, I find that there is insufficient RAM to step out to DOS from WordPerfect and run a file convert or do a chkdsk. Is there a solution to this, other than keeping two versions of my config.sys and rebooting as needed? The config.sys which allows use of the extended memory is as follows: DEVICE=C:\DOS\ANSI.SYS DEVICE=C:\QMSJS\JETSCRPT.SYS -P2 -I1 -L2 DEVICE=C:\DOS\HIMEM.SYS DEVICE=C:\EXMM.SYS -r3 -e1400 FCBS=1,0 BUFFERS=12 FILES=30 The Jetscript Postscript driver must remain in place. The ansi.sys device only runs my clock display, and could be sacrificed if needed. To get the extra RAM back for DOS-from-within-WordPerfect, I have to disable line 4 (EXMM.SYS - the driver from Zsoft) and reboot. Please e-mail me (jw2b@virginia.edu) and I'll summarize if there is interest. Thanks!

One response came from the author of Turbo EMS. He says that all expanded memory simulators (i.e. simulate expanded with extended) will grab about 72K from base memory (64K for the simulated expanded memory pages and about 8K for the driver). Turbo EMS does however have a command to return the 64K to active use when needed so only a small amount of memory remains unavailable. Don't know if other like programs have this feature and haven't bought Turbo EMS yet to see how well it works.
