detection, and BIOS-BMC interaction.
How is data input to this memory? Programming CPLD(s) requires a vendor provided
logic file and loader program which is executed by
booting up the system from a floppy or OS based
executable containing the logic file and the loader.
System loaded with arbitrary data in CPLD(s) would
not operate.
How is this memory write protected? Software write protected
Remarks Need AC cycle after updating CPLD

Details
Size: 8 Mb
Type: [e.g. Flash PROM, EEPROM]: Flash
Can user programs or operating system write data to it
during normal operation?
No
Does it retain data when powered off? Yes
Purpose? [e.g. boot code] Controller Firmware & configuration data
How is data input to this memory? Loading flash memory requires a vendor provided
firmware file and loader program which is executed by
booting up the system from a floppy or OS based
executable containing the firmware file and the loader.
System loaded with arbitrary data in firmware memory
would not operate.
How is this memory write protected? Software write protected
Remarks There is a quantity of “2” SPI flash on the IO planar.
Both flash parts are for the two 5709C controllers.
