Editor's note: This directory contains modified versions of 2 memory- resident disk drivers. The originals are also on this tape! (See, there really is some advantage to having the tape out so late)! The driver FXDRVX.MAC is modified from [300,140]FXDRV.MAC, while SLDRVX.MAC is modified from [343,32]SLDRV.MAC. In both cases the modifications are to provide for a call to $FORK in the middle of long transfers, thus allowing other drivers to have access to the EXEC. Otherwise your system response-time for interrupts will be significantly degraded.
