hi
I am new on this list and my name is Philippe.
I used to make some programs on windows but wanted to trye on linux.
I have a problem with a small prog i had done for windows witch play
sounds on the fm chip of a sound card.
But when i translate it on linux, it doesn't work any more.
It compile and link correctly(nasm), but on execution it writes:
segmentation fault!
I post you the sources at the end of this message.
I had an other question:
Where can I find bible of all the interruptions and what is the name of
it?
Philippe

Maybe You have no permission to write to that ports.
Use io_perm syscall to set it.
Also this king of programming is not good choice for linux. Use kernel to
do the dirty work. You can use a "services" (ioctls) of sound driver to
produce sound. I think there is an tutorial on www.linuxassembly.org
for a sound too.

It is called Ralf's Brown Inetrrupt list.
Use google.com to find it (it was on Simtelnet mirrors)

direct port access requires 'root' rights and the concerning ports
being enabled, with sys_ioctl or sys_ioperm. - e.g <man 2 ioctl>

basically, there is one interrupt and several sub-codes, passed w. eax.
'the' bible doesn't exist, linux is in a somewhat 'fluid' state and, badly
documented. Paricularly no aequivalent to 'RBIL' but, you might get some
help from my syscall pages where i collect whatever i find fairly reliably
documented/tested.
