Try this solution (it does a warm boot): ------------------------------ debug < BOOT.DTA > NUL ------------------------------ The contents of the file BOOT.DTA is: ------------------------------ e 40:72 34 12 g=ffff:0 ------------------------------ This set a warm-boot-flag into the bios-area and then starts the boot-process without a memory-test (it's faster). +------------------------------------------------+ | Rainer Gerten | | University of Kaiserslautern | | West-Germany | | Mail: gerten@uklirb.informatik.uni-kl.de | | Phone: 49(631)205-2510 | +------------------------------------------------+
