[XP one size fits all or separate slipstreamed disk for each mfr?]

The generic is a BYOC machine from off the shelf parts. The XP Disk is straight from MS and was purchased as an item at computer store and not preinstalled.

The reason for my initial question was that recently when trying to determine a problem, I pulled a disk from the PowerSpec and attempted to use it as the boot disk a HP machine. Apparently, HP has something in the BIOS or shadow boot that will not boot a non-HP disk.

Thx

Around the house have Dell, HP, PowerSpec and generic machines. Do I need to slipstream a disk for each brand from their disk or will the generic work for all?
