You should alter your config.sys so that you have a special option for booting when you plan to run Executor. In it, you should cut out soundblaster (it doesn't work right now; you can restore it later) and trim your CD-ROM drive buffer down to 256k or so. That should leave you with about 7.5 MB left at this point.

You can then trim the smartdrive down to 512k, so you'll then be at about 6 MB left.

Well, now you can run a 1 MB app and still have 5 MB left. Gene> Forget about Gene> running multiple copies of Executor for multitasking... you Gene> can't even run it once! Executor itself takes up about 1.5 MB of memory before doing anything else, so you're now down to about 3 MB left, which means you can get about a 1.5 MB ApplZone and still have room to avoid paging.

Gene> What should I do? I would suggest running Executor from DOS instead of from Windows. Word 5.1a runs fine on our 75 MHz DX4 laptop with a 512 kb read only smartdrive. Other than trimming the buffers, like I suggest above, programs require memory -- Windows requires memory, Executor requires memory, the programs that you run under Executor require memory.

Executor is a windowing operating system all by itself, *and* a synthetic CPU. There's no way we can significantly trim its memory requirement, but if you cut out Windows and big buffers, you should be able to run on an 8 Mb system without much hassle.

Hmmm... that's very surprising to me. If DOS shows the file as 400 MB, Executor should think it is 400 MB, too. I've had other people say that it works, although the compression ratio that they get varies greatly depending on how much free space is still "virgin". --Cliff ctm@ardi.com
