[wellylug] Werid Network Problems + IRQ Conflict

[Klenner, Colin]

You should go to the BIOS of your machine.
 
Bus mice use IRQ-2 cascaded to IRQ-9 if required. 
ISA network cards are normally set to default to IRQ-3 or IRQ-4, which are
also the IRQ's for serial ports. A serial mouse may interfere with the ISA
NIC if they are using the sale IRQ's regardless of the interupts they use.
For instance if the mouse if on COM1 and the NIC on COM3 they both use IRQ-4
and can interfere with each other.
