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.
