PIO modes

[ITGirl]

i know im going old school..but was just wondering

what sort of bus is required to operate PIO mode 3 or 4?

PIO modes 3 and 4 would indicate something to do with ATA. These modes were officially defined in the ATA-2 standard (1996). So one would need ATA devices that conform to ATA-2 or later.
