As said, keep me updated on it.
other drivers/tsrs hooking interrupts are not that big a problem because Jemm386 makes a snapshot of the current IVT when it is loading and usually it loads pretty early, just after the XMS host (the XMS hosts most likely will hook int 15h only). some days ago Jemm386 has been updated and includes the FASTBOOT option already - which might even work with FreeDOS ... with the help of a small device driver exclusively written for this DOS :). Of course, for FreeDOS running in DosEmu the FASTBOOT option is absolutely useless. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
