JG>Ok, I'm writing a small bootstrap loader which loads whatever is on Sector
JG>2 of a 1.44M Floppy into memory at 9000h:0000h and runs it.  That program
LG>is fine.
JG>It doesn't seem to ever return from Int 013.  That's been tested with a
JG>call to the teletype output of Int 10.  I'd put the TTY Code to print a *
JG>before and after the Int 13 call, and it would only print one of the *'s.
LG>(yes, I did preserve the registers)
My guess would be that some TSR program is using that memory, and when
whatever interrupt is supposed to trigger it happens, it goes there and finds
the code changed, and doesn't return properly.  There may be other
explanations, but I can't think of any right now.
