If you have the Dell CD you don't need this. In setting up this procedure I compared a Dell CD to a hologram CD and wrote a program that would generate the files that were different.
I have a Dell SP1a slipstreamed to SP2 CD. However I do not like the branding and other customised files and wish to OEMBIOS process a generic MSDN SP2 CD. I used Beyond Compare to compare the I386 folders of the Dell SP2 CD & MSDN SP2 CDs. Files differing are:
Besides the OEMBIOS.* and SETUPP.INI differing, why do you think the other files would differ? Was it because of Dell's SP1a or Dell's customisation to these files? And back to the main query, is it possible to use Dell OEMBIOS files into MSDN and change SETUPP.INI to accept OEM keys?
