**82497/492   Cache Controller / Cache RAM (for P54 Pentium)    <Nov94

The info and features section have  been solely sourced from the first
source.   The  second source  provides  far  more detail.   Additional
information in the configurations section  and below have been sourced
from the second.

"Although the 82497 Cache Controller  is part of the Pentium processor
(735\90, 815\100, 1000\120, 1110\133) CPU-Cache Chip Set and the 82496
Cache  Controller is part  of the  Pentium Processor  (510\60, 567\66)
Chip  Set, the  two parts  are functionally  identical except  for the
differences noted in this section." - p491

Aside  from some  minor  differences in  pin  configuration, the  main
difference is the direct support  for 3.3V processors. This chipset is
still a 5V part. The cache operates at bus speed, max 66MHz.


This  chip was  used on  the Pentium  90MHz CPU  complexes of  Intel's
Xpress  platform.   Specifically  the BXCPUPENT90  (Single  90MHz,  16
82492s). Also found on IBM 9595/Server 500 Pentium 90MHz complexes.

Chips:
[VT82C694X or VT82C694MP] (North Bridge)
[VT82C596B or VT82C686A/B]] (South Bridge)
CPUs:          Single or Dual (VT82C694MP only) P-III, P-II, Celeron
Bus Speed:     66/100/133 MHz 
DRAM Types:    PC100/PC133 SDRAM, Reg SDRAM ESDRAM VCSDRAM 
Memory bus:    66/100/133 MHz 
Max Mem:       2 GB, rev CE and later possibly 4GB 
ECC/Parity:    Both
PCI Bus:       2.1 
AGP speed:     4× 

Only 6 banks can be used with 133 MHz RAM, 8 for 100Mhz. Reg RAM may 
be different.

Apollo Pro 133Z [VT82C694Z] is an ASUS OEM version of the VT82C694X. It
could be pin compatible with the VT8605 (PM133).
	 
Apollo Pro 133+ Seems to be the same as the 133A.

VT82C694A  is an early internal (to VIA) name for the VT82C694X.
