Epson Epson User Manual

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 up to two high-performance PCI
cards, such as high-speed video cards. 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
cards such as fax/ modem cards, sound cards, and SCSI (Small

Computer System Interface) cards.

The computer’s system and video BIOS are contained in a flash

memory device on the main system board, which you can
upgrade 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, S-bit flash device.
