ISA and PCI Expansion Buses
Your computer includes expansion buses for two types of
option cards: ISA and PCI. The PCI bus provides extremely fast
data transfer (33 MHz) for a high-performance PCI card, such
as a high-speed video card. PCI cards use plug and play
technology that automatically configures resources used by the
card, such as interrupt requests and memory addresses.
The ISA bus transfers data at 8.33 MHz for up to three 16-bit
ISA option cards. You can use these slots for standard ISA 8-or
16-bit cards such as fax/modem cards, sound cards, and SCSI
(Small Computer System Interface) cards.
SVGA Feature Connector
If you install a high-resolution graphics adapter card or a
full-motion, multimedia card, you can connect it to the
computer's SVGA (Super Video Graphics Array) feature
connector. This allows you to use the adapter's special graphics
features while accessing the standard SVGA signals provided
by your main system board.
System and Video BIOS
The computer's system and video BIOS are contained in a flash
memory device on the main system board, which you can
upgrade using special software, without replacing the chip.
Your computer supports shadowing of the system and video
BIOS to allow BIOS routines to run from fast, 32-bit RAM
instead of from the slower ROM devices.
