Revisons to COPYFAST.ASM  version 4.3

The file CPYFST43.ASM has been revised and named CPYFSTU.ASM (COPYFAST
UNIVERSAL version). This is due to the fact that COPYFAST will now
extract information from the BIOS Disk Parameter Block and calculate
the track number for the first data track (2 for most 8" disks and 3 or
4 for 5-1/4" disks) and the total number of tracks on the disk. The BIOS
sector translation table is also used for data track reads and writes.
This should eliminate the need for a custom version of COPYFAST for every
disk format. While these modifications yield a more universal version of
the program, the copy speed may not always be as fast as possible.
This applies in particular to the IBM 3740 SS/SD 8" disk since it has a
sector skew of 6 and many controllers can easily handle a skew of 1 or 2.
If you copy a large number of a certain disk format it may be worthwhile
to set the BXTBL equate to FALSE in the .ASM file and insert read and
write skew tables that are optomized for the format of interest. The
current tables are for the IBM 3740 format.

CFU.COM is the general version of COPYFAST.
CF3740.COM is the IBM 3740 8" version of COPYFAST and may need
customizing for your controller.
