programming voltage is always supplied to the devices and the Flash
contents may be modified by executing the proper program command
sequence. Refer to the third-party data sheet and/or to the PPCBug
Firmware Package User’s Manual, listed in

Flash contents.
RAM300 Memory Module
The RAM300 is the ECC DRAM memory mezzanine module that
(together with an optional PCI mezzanine card) plugs into the base board
to make a complete MCP750HA single-board computer. See
Hardware Preparation and Installation
, for more information.
RAM300 modules of 32, 64, 128, or 256MB are available for memory
expansion. The ECC DRAM is controlled by the Falcon memory
controller chip set. The Falcon ASICs perform two-way interleaving, with
double-bit error detection and single-bit error correction.
In addition to the ECC DRAM, the RAM300 module supplies 8MB of
additional soldered-in 64-bit Flash memory. A jumper header (J9) tells the
Falcon chip set where in memory to fetch the board reset vector.
Depending on the configuration of J9, resets execute either from Flash
memory Bank A or from Bank B.
Compact FLASH Memory Card
The MCP750HA supports a single EIDE compatible Compact FLASH
Memory Card off of the PBC Primary EIDE interface. Currently available
Compact FLASH memory cards provide from 2MB to 96MB of formatted
capacity. Once configured, this memory will appear as a standard ATA
(EIDE) disk drive.
TMCP700 Transition Module
The TMCP700 transition module (see
Preparation and Installation for TMCP700
, for more information) is used
in conjunction with all models of the MCP750HA base board.
