I too have a 2100A, its rackmounted. The 2100A differed from the 2100, in that 
it had a "segmented" pci bus,a different I/O module, and some other subtle 
differences in the SMP frequency timing, which so far, no one has got a handle 
on, either with netbsd or freebsd.

I was working with Andrew Gallatin, who wrote much of the original code for 
the AS2100 for Freebsd. Unfortunatly the machine was a production server 
running VMS, and I was only playing with it when replacing some disks, so I 
was not able to help find the problem. I too had tried the RH 7.2 
distribution, which crapped out on me during the install. I never got around 
to try the debian or gentoo distribution to see if they had incorporated the 
RH and HP code from the wrapper cdrom.

Interestingly, the machine installed and ran FreebSD 4.4 in uniprocessor mode 
fine. I also managed to boot a uniprocessor netbsd kernel..1.5.2 ?? or 1.6 in
all the way up to the disk recognition where it refused to recognized any scsi 

I too would like to see a bsd on these machines, The one I have has 4 275Mhz 
processors and 1 GB of memory, so it should be pretty zippy.

If you have the time and the understanding you might work with Andrew and get 
to the bottom of the problem, He just need someone to apply patches and run 
the test kernels.
