When using this limiters... Are himemx and jemm386 better on the whole line then himem / emm386? Or does it introduce new problems with legacy apps? >> FreeDOS KEYB 2.0 (pre4) >> Critical error: cannot allocate memory. >> DOS reported error: 8 > > For DISPLAY, you would expect XMS to be used, but for KEYB? > Did you try without EMM386 and/or without HIMEM? - with himem and without emm386 it was working - without himem and without emm386 it was working - with himem and with emm386 but with noems it was working >> DEVICE=C:\FDOS\BIN\EMM386.EXE MAX=30000 NOEMS >> When using NOEMS the bug did not appear. >> (But therefore still others, >> crashing extenders and such.) > > With NOEMS, there is no page frame, and DOS can use more > UMB for other things, so the bad area is touched later. > You should try to find the right X=?-? option for EMM386.

I have mouse and keyboard connected both thought real PS/2. But this was the helping point anyway. As I am forced to enable either USB keyboard support and/or USB mouse support in BIOS in order to boot from USB it was enabled (for real, this is a known bug). When I boot from eSATA or IDE I must remember to turn off USB keyboard/mouse in BIOS, then ctmouse/FreeEDIT and keyb are working. When booting from USB I must have USB keyboard/mouse in BIOS enabled, then ctmouse/FreeEDIT and keyb are working. > Did you try CTMOUSE 2.1 already?

Well, I've googeld myself this setting a while ago because I did run out of space when using complex batch. It was working well for a long time and therefore I like to keep it in case it can make no trouble. > That most likely means that some of your UMB area is bad! A part of the problem has been solved already. But when booting with himem only it says "UMB unavailable". Do you think this would disappear when I downgrade from 2 GB (2x 1 GB bank) back to 1 GB only? -mr ------------------------------------------------------------------------------ Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.
