After looking into this some more, Simply switching the #CE pin may not be sufficient as the chip is still operating and can interfere with the bus.
After looking into this some more, Simply switching the #CE pin may not be sufficient as the chip is still operating and can interfere with the bus.
However, it appears that whilst the #reset pin is tied low, all input/output pins on the flash are in a state of high-impedance. We should be able to simply ground this pin to disable that chip, rather than lifting the #CE pin.

EDIT: it seems it is sufficient to use only CE# as several tests (some on this very same page) prove.

This method relies on entirely lifting the existing NOR flash chip and planting a 256mbit chip, you could lift Address pin 23 and have a switch to tie this low or high to switch banks. A compatable samsung k8p5615uqa chip ([http://www.bdtic.com/DataSheet/SAMSUNG/K8P5615UQA.pdf datasheet])

This looks like it could work, as per the spansion and samsung charts, when using autoselect commands etc, it does not care about the state of pin 23. So there should not be any interference.

Only a single version of VFlash is stored on flash in NAND consoles, and a single copy is stored at the beginning of the PS3 hard drive on NOR consoles. Because the firmware stored here doesn't match that stored on flash, you would have to reinstall the rest of firmware everytime you switch. We could possibly overcome this limitation by patching the storage manager to redirect vflash to another region of the hard disk.
