Hello!
I have the exact same problem that sgt Stryder has when I try to install WinXP from CD on my dual Opteron based machine. In German it looks like this:
Fehler:
Installation Failed : D:\I386\asms. Error Message: Unzulässige Funktion.
***
Schwerwiegender Fehler:
Eine der für die Installation benötigten Komponenten konnte nicht installiert werden.
Unzulässige Funktion.
***
This does not happen when I try to install from a network source in our company (completely different hardware and no installation from CD).
I already tried to remove ALL updates, WMP11, IE7 and the winnt.sif but it does not change anything.
Attached two HFSLIP.log files in one ZIP: One with "nothing" integrated and one with WMP11, IE7 and patches. Both "integrations" cause the same error.
Maybe this might help: Compared to the source I use in our company I already added a SATA driver (SI3114.sys). This is a "known good" driver integration that I used several times. I also tried to do a test installation with this original WinXP SP2 source + Si3114 driver and it worked perfect.
After I used this source with HFSLIP it failed with the errormessage from above.
