[net.micro] IBM PC fast floppies

spoon (07/29/82)

The recent issue of 'PC Magazine' is distributing the listing of
an IBMPC basic programme which will double the speed of the
floppy disk's sold with the IBMPC.  The programme creates a file
called 'speedup.com' which patches disk timing parameters in the
IBM DOS to less conservative values.

25 FIELD 1,1 AS N$: FOR I = 1 TO 37
30 READN N: LSET N$ = CHR$(N): PUT 1
35 NEXT: CLOSE: PRINT "CREATED": END

50 DATA 250, 190, 26, 1, 185, 11, 0, 243, 164
55 DATA 51, 192, 205, 19, 139, 215, 205, 39
60 DATA 223, 2, 37, 2, 8, 42, 255, 80, 246, 0, 4
65 DATA 3866

This programme is on page 151, Volume 1, Number 3.
If you put the 'speedup' command in the autoexec.bat file
you can hear the disk's speed change immediately afterward.
