checking number of parallel ports installed and their port adresses

[Alexander Best]

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.
