notes Notes

The Promise 20230 & 20630 chips are very similar.

20230 offers:

  • single IDE port
  • PIO4 modes on amenable storage devices
  • IRQrdy modes depend on the controller implimentation

Drivers & BIOS are compatable between the Promise 20230 & 20630, but the WDMA modes require the 20630 chips.

Promise 20230 & 20630 chips are supported by XTide Universal BIOS 386L module in a beta state as of XUB r629
