This is a similar idea to how SLIC modification is being done for SLP Vista. I hope people still have enough interest in this older OS to start something up. I have access to a Dell Inspiron 6000 and can provide a dump of the DSDT. Also, I have a royalty xp pro disc, and can extract the oembios files. I suspect that XP uses DSDT since it's the only table that has a Creator ID by MSFT. Anyone have any ideas where to start? I imagine it isn't as simple as just modifying the OEM ID and OEM Table ID's. When I scanned through the DSDT table, I found a few entries on the different versions of Windows. Hope this goes somewhere Any biters?
