Hi,
i tried to access a pc-bios from within a kernel module as follows:
short in = 0x6f0a, out;
asm (
"movw %1, %%ax;"
"int $0x15;"
"movw %%ax, %0;"
:"=r"(out)
:"r"(in)
:"%ax"
);
printk("%x\n", (int) out);
It seems, that the interrupt to bios is ignored, because nothing happens. Has anyone some link, example code or tip, that could help?
Thanks,
Matthias
