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.
