I assume i must be looking at this out of context somehow.. ;-( But since we are on the subject of int calls, how does one do it from freebsd anyway? I got some mail from the guy who ported this linux mpu401 driver ( to the sunos flavor that runs on a 386 sun ) that i wanted to hack on. He gave me a suprisingly helpful collection of boxes that i needed check off before i could do something like this. The only one left to sort out is how to do interrupts. I tried : grep int /usr/src/sys/i386/isa | more but all i found was printfs and variable declarations :-) ( *lots* of printfs and variable declarations ) Finally, what is the flag to gcc that gets it to emit the *.s file ? I thought it was : gcc -s foo.c but that does not seem to doing it! > Bruce > thanks gang! ******************************************************************************* John Utz spaz@stein.u.washington.edu idiocy is the impulse function in the convolution of life
