Notes
The Promise 20230 & 20630 chips are very similar.
20630 offers:
- 2 IDE ports over the single port on the older chip
- Chip can talk WDMA to storage, but transfers from the chip to the PC are still PIO
- IRQrdy modes depend on the controller implimentation
- improved performance when everything else is the same
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
