Hello!
I've a Wyse pc286 model 2108 (8MHz '286), and the Norton SI utility
lists the computer name as "IBM XT/286". What is that? I thought
that the IBM PC/XT had an 8088 processor. Shouldn't the SI list the
computer name as an AT?

The XT/286 was made about two years after the introduction of the AT. It had a 286 processor in an XT case, which meant that full-height AT cards would not fit. It didn't last too long -- dropped quietly from IBM's line after about a year or so. Jason Deines roller@jessica.stanford.edu

As to why it shows up, IBM places a marker in their BIOS around F000:FFFE (exact address may be different). This is a 1 byte marker. I can't find the exact values (It was described in one of Byte's IBM special editions) but it's something like: FF = PC FE = XT FD = AT FC = PC conv FB = XT/286 FA = PS/2 etc... Note to Flamers: These values are from memory, and are probably wrong. They are posted to get across the point as to WHY wysepc286 says XT286 under norton. So, your Wyse's BIOS has an FB (or whatever) in the critical spot,and Norton SI thinks you're an XT/286.
