Technical Information 1-3
n
support for memory expansion board containing a minimum of 16 megabytes
(MB) of dynamic random access memory (DRAM) in single processor
configurations
8-slot memory expansion board accepts 36-bit, 70-nano second (ns) single-
inline memory modules (SIMMs)
memory expandable to a maximum of 256 MB of DRAM using either
1-MB x 36 bit, 2-MB x 36 bit, 4-MB x 36 bit, or 8-MB x 36 bit, 70 ns
SIMMs mounted in the 8-slot memory expansion board (see Section 3 for
memory expansion procedures)
supports base and extended memory
n
16-kilobyte (KB) primary cache (8 KB data and 8 KB instructions) integrated on
the Pentium processor
n
256-KB synchronous secondary cache in single processor configurations
n
high bandwidth PCI local bus
supports burst modes that send large chunks of data across the bus, allowing
fast displays of high-resolution images
eliminates data bottlenecks
maintains maximum performance at high clock speeds
provides clear upgrade path to future technologies
n
Integrated 32-bit bit-block-transfers (BitBLT) graphics accelerator that uses the
PCI local bus
supports 640 x 480 and 800 x 600 resolutions with 16.8 million colors (24-bit
True Color), and 1024 x 768 resolution with 256 colors
2-MB of 45 ns video dynamic RAM (VRAM) (eight 256K x 8 chips soldered
on the system board)
supports a linear frame buffer with full PCI burst write support
