awkduck Posted January 13, 2022 Share Posted January 13, 2022 (edited) I have this 2003 era laptop, with soldered ram (512Mb). But the initial 640k (and some above) are fine. The laptop includes an additional 512Mb memory stick. With Linux I can use a kernel boot parameter (mmap) and tell the OS to ignore the bad on board memory range. It runs very stable that way, other wise the motherboard heats up and the usual bad memory issue arise. What is the best way to deal with this in Win9x? A himem.sys configuration? Or maybe eat up the bad memory range with a ramdrive, that I never use? Edited January 13, 2022 by awkduck Link to comment Share on other sites More sharing options...
MERCURY127 Posted January 13, 2022 Share Posted January 13, 2022 (edited) or use dos ramdisk like SRDISK, or write own pre-himem dos driver like BURNMEM, which will hide selected memory regions from himem via int15, or mod open-source himem XMGR for exclude some addresses... or use himemx or old himem from msdos, which [can be] limited first 64 MiB.

jumper Posted January 14, 2022 Share Posted January 14, 2022 Reserve custom memory ranges in: My Computer -> Properties -> Device Manager -> Computer -> Properties -> Reserve Resources If you can't boot in safe mode, exactly how many megabytes of low memory can be safely used?
