FAIGA FAAVAEVIEW
O le S4967 Rev: 2B.31 486 Cache system board E 2/3 Pepe AT-tele, atoatoa PC / AT fetaui ma ofoina atu tulaga mataʻina faatinoga ma foliga.
Faatasi ai ma le 128K/256K/512K/1M cache memory i luga o le laupapa, o lenei system board O se masini saoasaoa tele e fetaui lelei mo le fausiaina o komepiuta patino po o tulaga faigaluega.
O le $4967 Rev:2B.31 486 Cache system board ua mamanuina ma le SIS 85C496/85C497 chipset lea e matua tu'ufa'atasia. Faatasi ai ma lenei chipset, e naʻo ni nai mea faʻapitoa
masini e manaʻomia, lea e mafai ai ona tuʻu le 4 faletupe manatua i luga o le laupapa. Ole tele ole manatua e mafai ona fua ile 1 MB i le 255 MB.
FAAMATALAGA
Ole $4967 Rev:2B.31 486 Cache system board e lagolagoina (pe aofia ai) vaega nei:
* Lagolago
Intel 486SX/SX2/DX/DX2,DX4(3.45V),P24D,P24T AMD DX,DX2/DX4(NV8T),OX2/DX4(SVEB) Cyrix SX/DX/DX2,DX2-V66/VB0(3.45V),DX4(3.45V), 15×86 (3.45V) in 25/33/40/SOMHZ
- Fuafua ma SIS 85C496/85C497 Chipsets
- Lagolago 128K/256K/512K/1M 2nd Level Cache
- Lagolago 4 DRAM Faletupe. O le DRAM e mafai ona bul ma elther Single-Sided poʻo le Faalua-Sided SIMMs. Ole maualuga ole manatua e o'o ile 255MB
- O le ata lafoia o le RAM mo le BIOS ma/po'o le vitio
- Tolu 32-bit PCI avanoa pasi fa'apitonu'u, fa 16-bk fa'alautele avanoa

A'o le'i sauni le faiga e fa'agaioi, e tatau ona fa'atulaga meafaigaluega e fa'ataga ai galuega eseese i totonu ole faiga. Ina ia fetuutuunai le $4967 Rev:2B.31 Cache system
laupapa o se galuega faigofie, na o ni nai Jumpers, connectors, ma sockets e tatau ona filifilia.
CACIIE FAAMANATU SOCKETS
O le $4967 Rev:2B.31 Cache system board e lagolagoina 2 faletupe o le SRAM lea e maua ai le 126/256K/512K/1MB o le manatua o le cache. O lo'o lisiina i lalo le laulau o lo'o i lalo
