Upgraded with latest CPLD code, 1MB flash chip and xblast OS installed.
When installing, make sure to leave BT and HD disconnected (these serve to force booting the bios banks in case of recovery).
D0 must be connected to d0 on 1.0-1.5 and L1 on 1.6.
The install is otherwise the same as a normal aladdin.
Pete @ mmmonkey.co.uk has done a guide for the xblast aladdin, might also be worth reading that here
