NAME
GETSYS.HEX Utility to extract CP/M
SYNOPSIS
i8080 -b getsys.hex -A . -B cpm20.com
DESCRIPTION
GETSYS extracts CP/M operating system from a standard CP/M master
floppy disk.
The parameter of -A option must be . because the source disk drive
always is physical. The parameter of the -B option can be any file name.
However, the use of a file name, "cpm20.com" is recommended.
You need to create "cpm20.com" before executing GETSYS.
For example, on MS-DOS, you can use the command
type null > cpm20.com
to create a new empty file, "cpm20.com"
Since GETSYS assumes that BIOS of I8080 handles the standard CP/M
6 sectors skew scheme, the program translates the sector number when
reading a physical disk in order to compensate for the skew.
WARNINGS
The filename specified with -B option must exist before the execution
of the program.
If the size of the file is over 8 Kbytes, the extra information will
still be kept.
GETSYS will not do any error checking during the execution.
