Not my month this - you name it, and its gone wrong, packed up, vanished or 
plonked itself nicely into the bizarre category.

Fwiw, it appears I have a cheap Alladin V clone. Booting can be achieved by 
disabling power management in the BIOS *plus* fiddling with an IRQ3 option 
that I don't fully understand (can't get a decent bios manual). That'll get 
the machine to boot.

Next problem manifests itself as dodgy ram - gcc & bz2 failures. Default CS 
latency is "Auto" but setting it specifically to match the ram (CS=2) 
improves things greatly. The north/south bridge chips don't match any 
datasheet - iirc it appears one is off one particular release series, the 
other off the next mobo release.

Finally nailed the remaining reliability problem down to UDMA. Moment I turned 
it off, spurious faults went away and haven't re-occurred since. Obviously 
this mobo is a pile of junk. On the off-chance there's useful info to be had, 
here's how it fires up currently...

I wouldn't mind a hint on the audio side? Card used to work fine in another 
machine running 4.7-REL (Ensoniq AudioPCI). I'm a bit loathed to mess with it 
indiscriminately 'cos toggling the UDMA on/off is a right royal pita.
