I have the whitepapers for the 1533/1543 ide ALI chipset, but no real time ti poke at them.........they appear to have s similar splitfifo like the VIA boards........ Making the kernel see them is easy, setting dymanic UDMA timing codes for the pci-config space is difficult, breaking the Simplex pre-commands is painful. Since I am hunting for a loaner board, and Michel Aubry (The VIA-IDE-Guy) is waiting on an ALI board........we are just waiting.
