MEMORY BUSES
The Intel 440BX/GX AGPset supports the system and memory buses at both 66MHz and
100MHz speeds. The 100MHz system and memory buses provide a higher bandwidth
path for transferring data between main memory/chip set and the processor.
DMA CHANNELS The SBC is fully PC compatible with seven DMA channels, each supporting type F
transfers.
INTERRUPTS The SBC is fully PC compatible with interrupt steering for PCI plug and play compati-
bility.
BIOS (FLASH)The BIOS is a Hi-Flex AMIBIOS with built-in advanced CMOS setup for system param-
eters, peripheral management for configuring on-board peripherals, PCI-to-PCI bridge
support and PCI interrupt steering. The BIOS chip is a boot block Flash device -
28F002BX-T120. The BIOS may be upgraded from floppy disk by pressing <Ctrl> +
<Home> immediately after reset or power-up with the floppy disk in drive A:. Custom
BIOSs are available.
CACHE MEMORY For Pentium III processors, the processor includes an integrated on-die, 256K 8-way set
associative level two (L2) cache. The L2 cache implements the Advanced Transfer
Cache architecture with a 256-bit wide bus. The processor also includes a 16K level one
