Hello:
First time poster!
I was wondering if anybody could provide any recommendations on how a design
should react to a PCI write to the Expansion ROM Base Address Region
(which is enabled)? Should I let the writes go thru to the "bit-bucket",
allowing the master of the message to think that the write was successful?
Or should I issue a Target Abort, as this is an illegal I/O Addressing Error?
Or should I allow for writes, with the possibility of corrupting on-board
Expansion BIOS data?
Any help would be appreciated!
