I think that's it.  Weirdly it occasionally booted right through but 
that was very rare.  Following the instructions on the FreeBSD ACPI 
website I dumped the code and recompiled it with iasl.  It found one 
warning about not returning a value to a function which a linux website 
noted which I fixed. 

With the new DSDT.asl installed it seems to boot on the second attempt.  
It just hung on the "Timecounter" line again, but a reset then a verbose 
boot and its booted all the way. <sigh>

Its now complaining of

can't fetch resources for \\_SB_.PCI0 - AE_AML_INVALID_RESOURCE_TYPE

It gives the same error message for PCI1 and PCI2 as well.

Not yet.  I'll look and see if that is possible.  One problem is that 
this box is designed and sold by IBM to run win2k as a NAS.  IMNSHO it 
would be criminally negligent to run Win2K as a NAS so we've never put 
it into production.  It's not supported like a normal PC and the IBM 
website is pretty bad.

The fan speeds change, obviously under bios control, but the bios 
settings expose no options to modify them.

I was hoping to use it as my desktop machine as it has dual 1.1Ghz PIII 
Xeons but but it's way too noisy, so if I can't get the fan speeds 
lowered then I guess I'll just disable ACPI and install it into the 
computer room as a 5.2 test box. :)

Thanks,

Carl.
