I have a Fujitsu-Siemens notebook. This PC has XP Home OEM, *portuguese* edition, as factory install, by SLP method. I tested the OS recovery CD supplied with this PC, and it works exactly like the unattended SLP CDs described in this forum. No activation needed. Perfect. Well, my problem is that I'm a bit old-school and I feel uncomfortable if my computer has an OS not in *english* language. So here comes my question: is it possible to build a new SLP CD for the installation/recovery of Windows XP Home, but in english language and still using the SLP OEM keys which came with my notebook? I tested a "generic" english OEM CD, with a unknown OEMBIOS files set. I copied the OEMBIOS and related files (pidgen.dll, setupp.ini, etc) from the portuguese CD into the english CD. Next, I installed this new CD using the SLP key from the sticker in my notebook, but in the end it still asked for activation. Is this a feasible procedure? What is wrong? Should I copy all the OEMBIOS file set from the portuguese CD, or just the four OEMBIOS files?
