[code for reboot deleted]

I have difficulty using this method. Whenever I have emm386 loaded (this is
microsofts expanded memory manger for 386), it clears the screen and garbles a
message, something about "EMM386: DMA mode not supported" then hangs forcing
a hard reset. It works OK if EMM386 is not loaded.

CTRL-ALT-DEL always works for me. I need to know how this accomplishes a warm
boot and duplicate that since the "standard" method described in this newsgroup
doesn't work.

BTW, it is a 25Mhz 386 clone, ECS motherboard, C&T neat chipset with AMI bios.
