Win2K sysprep for multiple motherboards

I am creating sysprep disk for our company. There are two major different systems we purchsed, here is a list of "CPU/Motherboard/Chipset" of them:

(A) Pentium 4 1.6GHz / Intel D845BG / Intel 845
(B) Pentium 3 1 GHz / Asus TUSL2-C / Intel 815EP

The goal I want to achieve is to have *one* sysprep disk work for both systems.

I created sysprep disk under a new OS build on system (A), it works verey well if I duplicate it and put into another new box with identical or similar hardware. It'll work as long as the mobos have the same chipset.

I am trying to make it work for system (B), I know I need to add some more information about the mass storage device of additional system into the section [SysprepMassStorage] in sysprep.inf. However I could not get it to work.

I don't want to give it up and end up with that I need two sysprep disks for two systems with different motherboard, that means when we start to buy some other new computer 3-4 month later, I need to create one more sysprep disk for it.

I am seeking a solution to let me *ADD IN* mass storage information into exsiting sysprep and it'll work for new mobo, I will appreciate any suggestion.

Here is my sysprep.ini:
