It's called MS UAA (google that) and it's a shame the system you have didn't document that.
I searched the forums here and found this is a fairly common occurrence,
but found nothing that fixed my problem.
I have a partition running XP with no problems. Created an additional new partition and loaded XP on it and have no sound, although the original partition still works fine.
I have PCI multimedia audio controller by Realtech, so downloaded ac97 from this site. when starting installation got error "...not passed window logo testing etc....." I chose to continue anyway and
got the blue screen.
The sound on the original partition still works fine.
Please what can I try next.
Thanks for your time.
