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.
