Topic: how create my own DriverPack?

i have laptop Acer Aspire 1690 with Windows XP x86.
i'm trying using the DriverPacks Base 10.06. i download the Sound A and B Packs and i add them on Windows XP iso.
until here fine. i installed normaly, and all drivers was installed(except the card reader and other). the sound driver isn't working and i don't know why. it's 'Audio_Conexan_6.13.10.8335_XPx86'. i get '!' by some reason and i don't know how change the Sound A or B.
so heres my question: how can i use\add installer drivers on DriverPacks Base 10.06? or i must create, 1st, the Driver Pack with my laptop drivers?
