TESTMBRC
TESTMBRC is a 'compact' version of TESTMBR.
TESTMBRC : 4 KB
TESTMBR : 42 KB
It is intended for use, together with other programs, by a batch file on a floppy disk. 4 KB is only about 1% of a 360 KB boot floppy.
It runs the same tests of the first sector that TESTMBR does.
There is no screen output.
What is output is a 'DOS error level' (i.e. something that a batch file can use to detect success/failure of TESTMBRC).
DOS error level of 0 = Success
DOS error level of 1 = Failure
Like TESTMBR, if the tests are successful, TESTMBRC will restore the first sector to how it found it (whatever that was, blank or otherwise).
Hard drive 0 versus hard drive 1
By default, TESTMBRC targets hard drive 0 (normally appears as logical drive C:).
To target hard drive 1 instead, execute TESTMBRC with the HD1 switch, as shown below.
testmbrc /hd1
