hi there, i've written an app in c (and a bit of asm) which needs to do raw parallel port io using the i386 opcodes in/out. to get the number of available parallel ports installed and their addresses i open and mmap /dev/mem and read the address-values from the BIOS area @ 0x408. is there a better way to find out the number of parallel ports installed and their addresses? cheers.
