Fast and slow processor speeds available;

fast is the speed of the processor and slow

is 8 MHz; from the MS-DOS prompt,

speed selectable by pressing Ctrl Alt -

(slow) or Ctrl Alt + (fast).

8MB RAM standard using SIMMs;

expandable to 128MB using 1,2,4,8,16,

and 32MB SIMMs; SIMMs must be

tin-plated, 72-pin, 32-bit, fast-page mode

type with access speed of 70ns or faster

128KB Phoenix* system BIOS, video BIOS,

and SETUP code located in a flash

memory device on system board

1MB DRAM on main system board;

expandable to 2MB using two 512KB,

40-pin, SOJ flat pack video DRAM chips

Supports shadowing of system and video

BIOS ROM into RAM; shadowing

selectable in SETUP program

8 or 16KB of internal cache in the

processor; supports 128KB, 256KB, 512KB,

or 1MB of external cache with 32K x 8,64K

x 8, or 128K x 8,15ns or 20ns SRAM DIP

chips and a 32K x 8 or 64K x 8 tag chip

Math coprocessor built into the processor

on all DX and Intel Pentium OverDrive

processors

Real-time clock, calendar, and CMOS

RAM socketed on main system board with

integrated lithium battery

Provides PCI caching, memory and

control for the PCI bus, and the

two-channel PCI IDE interface; integrated

PCI bridge translates CPU bus cycles to

PCI bus cycles and CPU-to-PCI memory

write cycles to PCI burst cycles
