Slipstream + hotfixes

I am slipstreaming a new bootable CD. I have the original XP Pro CD & an ISO of same, the 'Network Installation' of SP1 and boot files.

My questions:

• My ISO already will create a bootable CD, so will I still need the bootfiles in the slipstream?
• Is SP1a worthwhile? Skip it for now, use SP1 and wait for next SP?

And most important:

• How do I slipstream the folder of updates post SP-1?

 

Hi, Pete ~

Thanks for straightening me out on the SP1a.

Do I need to extract the boot files from the CD using ISO buster since they already exist on my ISO of XP?

I thought Nero can extract the bootfiles anyway?

Anyone (you know who a really mean) had experience slipstreaming the hotfixes into a bootable??
