I would recommend the latter. You can run the printer driver without IRQs if you've got no other option. Of course, this will make it a CPU burner. It's only been invented to support printers or cables with a broken ACK signal. > Printer ports are generally found at IRQ 7. Many of them offer the option for IRQ 5 since this used to be the `official' LPT2 IRQ before IRQ lines got scarce, so IRQ 5 later became relabelled as ``generic IRQ''. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
