Cerbios ISO and CCI compatibility lists

UDMA Modes explained:

UDMA = transfer mode used by the kernel Increasing the UDMA mode has been profiled to improve some game load times in excess of 20% A full benchmark with SSD + StarTech shows disk IO is 70-100% faster across the board Increasing the UDMA mode will require an 80 wire IDE cable

The retail Xbox uses UDMA 2 (33mb/s) by default

The maximum supported UDMA mode by the Xbox southbridge is UDMA 6 (133mb/s HDD <--> CPU)

  • UDMA 6 is experimental, use at your own risk
  • UDMA 6 is confirmed to be working and stable with StarTech adapters
  • UDMA 5 and 6 are unstable on RXD-629A7-7 based adapters, but UDMA 4 seems okay
  • WLXKG-863B are the 'worst' adapters I have experienced working and are largely untested
