int13h always gives me error 9 on emulators but not real pcs
Posted: Thu Jul 14, 2005 11:00 pm
this is a weird thing that does not work a simple int 13h doesnt work
im now using bios.h as it dont have any int 21s or anything like that
i jsut can not get my write code to work it reads fine with no error
it seems i almost always get this error before i discovered bios.h could be used in an os and was trying to make my own functions
i do not get this when running the .com file from a widnows dosbox or when using emu8086's emulator and sending it the com file but in bochs and microsoft vpc i always get error 9
is there something im doing wrong
here is my code
edit:
compiled in turboc

there may be a few things in there that are obviously wrong but i was just testign them to see if it would work
