Fast and slow speeds available as described
in the table below; speed selection through
keyboard commands or jumper setting
At fast speed, DX2/50 and DX2/66
processors run internally at 50 and 66 MHz,
but run externally at 25 and 33 MHz; local
bus speeds for DX2 processors are 25 and
33 MHz, respectively
4MB RAM standard on a SIMM;
expandable to 64MB using 1MB, 2MB,
4MB, 8MB, 16MB, and 32MB SIMMs
(when available); SIMMs are tin-plated
(preferably), 72-pin, 32-bit or 36-bit,
fast-page mode type with access speed of
70ns or faster
Phoenix system BIOS, video BIOS, and
SETUP code located in 128KB EPROM on
main system board
1MB DRAM on main system board;
expandable to 2MB using two ZIP chips
Supports shadowing of system and video
BIOS ROM into RAM
Supports relocation of 256KB of memory
from A0000h to BFFFFh and D0000h to
EFFFFh to extended memory
8KB of internal cache on the CPU;
supports 64KB, 128KB, or 256KB of
external cache using 28-pin, 8 x 8, 20ns
DIP chips or 28-pin, 32 x 8, 20ns DIP chips
Math coprocessor built into DX, DX2, and
Pentium OverDrive processors
Contained in the 82C491 system controller
chip along with 64 bytes of CMOS RAM
backed up by a soldered NiCad
rechargeable battery
