IIRC, there's also a FDCONFIG setting of IDLEHALT which can already help somewhat. Outside of applications which constantly poll, it should reduce (virtual) cpu usage to less than maximum. Anyways, I just now booted up old QEMU 6.1.0 (64-bit) atop dead Win7 and used MetaDOS 0.7 (kernel 2041, 128 MB RAM, half of that is RAM drive) with old curl 7.64.1 to grab the relevant OW 2.0-c installer .EXE (which uses Causeway). Grabbing 140 MB with Curl took me five minutes. Installing a not-quite-full DOS toolset (roughly 33 MB) took two minutes. This was atop a virtual hard disk (FAT16) of 510 MB, no VT-X needed! NASM 0.98.39 (16-bit) built and worked okay, so did MiniSed, so did p2c. What didn't work was compiling TinyAsm (for some unknown reason, probably a bug). So I guess this issue can be closed. (Further testing results are still welcome.) _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
