I assume you are attempting to run a PWS within the server? Some of the older Sun Boxes had PC interface cards available, a complete Win computer on a card that plugged into a pci slot. You can probably still find those cards on EBAY
The newer DocuSP/FFPS servers are running on X86 boxes, that run XP without any difficulty -but of course not at the same time as Solaris. The PWS and Solaris could be dual-booted, but you would have to shut down one and re-boot to access the other. There is a Solaris virtual machine (downloadable from Sun) that runs within XP . . . . .but I've not seen an XP virtual machine that would run within Solaris
I assume that you are trying to emulate the old DT135 with its onboard diagnostic support? One of the reasons Xerox moved away from that model is it required a software upgrade to update documentation. That was a big deal with the tapes. And, we never had SearchLite on the DT135, an important tool.
If this is your goal, another solution would be a full sized PWS box and monitor/keyboard/mouse dedicated to the PWS. I've seen these at larger accounts with multiple DT/DP, they sit on a roll-around server stand that can be pushed next to the machine being serviced. The top provides a desk surface, other documentation is stored below. The top of the machine can be kept clear. A large monitor makes DC 330 input results easy to see from a distance. A wireless keyboard allows you to toggle an output from a distance.
Newer laptops provide a better PWS experience than the older ones (which you still see a lot of out there: -come on, come on . . .) Faster processors, more memory, and a 17" screen are all possible. Personally, I like fast, thin, light, durable, with a long lasting battery. This fits into the pocket of my soft toolbag. I consider it a tool and it's dedicated to that purpose.
