hiho everybody!

now i've got new problems! i'm grading up my shell with MultiTasking at the moment. my problems are these:

1. sometimes my OS doesn't react on the keyboard. but only with mt (multitasking). without it runs. but sometimes it also runs with mt. there is no rule, if it runs or not.
2. the OS sometimes print a " " at the beginning of the shell, without anything was pressed. but this happens only sometimes, too!

i hope you can help me!

mfg JN!

Do you use the timer , for your muititasking ?.

i use the int 0x1C which is every time called by the timerinterrupt 0x08 (ICQ 0x00).

how does your keyboard code look? and the shell code that handles the keypress?

i've no special keyboard code. i use the bios-int. and the shell works. the code waits a keypress and then move the ascii-code to the end of the string...

From my experience, timer IRQ can interfere with other int's (mostly keyboard ints) eg: slow them down or stop them working.
So i would say that could be your problem, but i mostly use my own ints from pmode, not bios, so could be wrong (did i say wrong, me ).

on my second test-pc the code works without any of the upper problems i saw! maybe it's something with the PC!
