xfrom is a playstation2 memory card flash chip hooked up to the DEV9 interface to be used as a flash memory for updates or bootloaders

Only functional use case is the PSX-DESR, although the SCPH-50xxx series have the drivers for it builtin, no network adapter with XFROM was ever found...

common use cases:

  • backup PSX Bootloader
  • replace PSX Bootloader
  • copy the flag files for the system to perform some tasks, like formatting the DVR area of the HDD, or repartitioning the disk, or extending the ps2 area to 40gig
