By the way, I'm pretty sure that there's no ATA controller in these.  Should just be good ole SCSI.  I mention this because I noticed Marius mentioned the ata driver in another message.

That's interesting.  Any chance we could try and boot one (preferably 3 or 4 times just to be certain) with the qfe/qge taken out?  The T1-200 supported a couple of quad gigabit cards (Sun P/Ns 501-6738 and 501-6522) which I've never seen before personally.  

I haven't ever worked with a T1-200 myself.  It does indeed look like an intermediate step, engineering-wise, between two very well-engineered machines (the T1-105 and the V120).  

Marius, I'm curious - the T1-200 has dual-eri interfaces on the mainboard, similar to the V100/V120?  

- mdh
