Upgrades
Cache Upgrade. This motherboard comes with either 0 or 512K L2 cache soldered directly onto the motherboard. The size of the cache will be autodetected. The cache is non-upgradeable.
CPU Upgrade. This motherboard has provisions to support Intel® Pentium™, Cyrix® and AMD® processors. The processor speeds are selectable with variable six jumper sets, three jumpers set to select the bus-to-core frequency ratio, and the other to select the CPU bus speed (60, 66, 75, 83, 95, 100 MHz). The bus-to-core ratio is either 2/11, 1/5, 2/9, 1/4, 2/7, 1/3, 2/5, 1/2 or 2/3 yielding the bus/core frequency. One Onboard DC/DC converter supply 2.2V, 2.8V, 2.9V and 3.2V to the CPU. Four 2-pin connectors. Zero Insertion Force (ZIF) socket. Uses the 321-pin Type 7 CPU Socket. Not keyboard switchable. Disable cache to slow down the system.
RAM Upgrade. Maximum on Motherboard: 256MB. Uses 16/32/64/128 MB DIMMs, 60ns or faster SDRAM DIMMs. Supports only non-parity DIMM modules. The 168-pin DIMM sockets will accept 3.5V 2MBx64 (16MB), 4MBx64 (32MB), and 8MBx64 (64MB) and 16MBx64 (128MB) DIMMs. Bank 0 will be populated as the default from the factory. No configuration jumpers: BIOS detects memory size, and memory type (EDO or Fast Page Mode). This motherboard will not accept 36-bit DIMM modules (parity).
- Video RAM : Some configurations of this motherboard come with 2MB of 100MHz SGRAM soldered onto the motherboard, other configurations have 4MB. The video memory is not upgradeable.
