MS-7260 Mainboard
32-bit PCI Slot

PCI (Peripheral Component Interconnect) Slots

The PCI slots support LAN cards, SCSI cards, USB cards, and other add-on cards
that comply with PCI specifications. At 32 bits and 33 MHz, it yields a throughput rate
of 133 MBps.

PCI Interrupt Request Routing

The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines
over which devices can send interrupt signals to the microprocessor. The PCI IRQ
pins are typically connected to the PCI bus pins as follows:
Order 1 Order 2 Order 3 Order 4
PCI Slot 1 INT E# INT F# INT G# INT H#
PCI Slot 2 INT F# INT G# INT H# INT E#
PCI Slot 3 INT G# INT H# INT E# INT F#
