I have a Gateway 386/33MHz w/ 4Mb (Micronics motherboard) and a Diamond Speedstar (Tseng ET4000) VGA card. I have had a serious problem with QEMM (v. 5.12) rebooting the machine when it tries to load. After a fair amount of experimentation, I have found that: device=qemm.sys x=a000-ffff i=c800-dfff fr=d000-dfff ram seems to work correctly all the time. But this limits me to 32K (c800-cfff) of available high RAM once I allocate 64K for the frame buffer (d000-dfff). Any time I have tried to include memory from e000-efff, or from B000-b7ff, the machine will reboot when trying to load qemm.` Does anyone know why this is happening, and/or how I could get more high RAM from qemm? -- Hal McMillan | "It's an ideal principle, which can be verified mcmillan@cis.ohio-state.edu | only under ideal conditions.

Turn off the BIOS shadowing functions.. let QEMM do it instead (ROM parameter).

And lo and behold, the techie on the other end nailed it! I needed to use the NOSH parameter. The manual indicated that was for C&T chipsets and I had not tried it before. Many people had suggested turning the hardware BIOS shadowing on or off, but that made no difference in my case. The techie was not able to help with my other problem: the fact that DV displays a control-break dialog box when I press ctrl-C in the PD version of emacs that I have. We tried all the keyboard interrupt values. He said that there are other programs that have this problem. In any case, I now use "RAM ROM NOSH" and have no problems. QEMM finds and uses the 384K of shadow RAM along with all my other RAM. I have upgraded to DOS5, and using DOS=high in my config I end up with about 637,000 bytes free. -- Hal McMillan | "It's an ideal principle, which can be verified mcmillan@cis.ohio-state.edu | only under ideal conditions.
