Question Disable serial and parallel ports


Hi,

I wonder if it is possible to disable the parallel port and the 2 serial ports within linux Debian. I have disabled them in the BIOS, but the system still shows IRQ 3,4 and 7 used by the ports. I have an older AT style system and like to free up these 3 IRQs. Does anybody know the trick?

Linux Debian 2.6.32-5-486, K6-III, ASUS TX97-e.

Thanks,

Mike.

A kernel compile should do it, as these are now regarded as ancient ISA stuff, you'll probably be able to lose them that way. Simply do not compile support.

As a bodge, you can hide the modules - move them out of the module tree. Run depmod just in case but that should do it. Move them to your homedir or rename them - parport_unwanted.ok or suchlike.

I resolved the issue: there is a jumper on te motherboard to disable parallel, serial and floppy controller at once! Nice feature from Asus :-)

Thanks for the help!
