That's a question to ask Microsoft. You need to build the CD with the drivers in it, you can't install them afterwards AFAIK.
There's an article on my blog about how to use AIK to build a PE CD, you might get inspiration from that. There's also a script with a whole bunch of drivers in it which might if you're lucky contain the ones you needed. You can probably see from the script how to install drivers into AIK.
When you create a BartPE CD, you can add the drivers to a subdirectory of %pebuilder%\drivers\SCSIAdapter and copy the drivers in there. The will be added to the BartPE CD automatically when building the CD.
if you rebuilding the ISO or maybe using pe2usb to USB stick for usbbootable.
then copy the driver into \I386\SYSTEM32\DRIVERS and edit the \I386\TXTSETUP.SIF to load the driver during boot.
note: in usb I386 renamed to minint
Drop your SATA driver plugins to the C:\pebuilder3110a\plugin folder. Prior to writing the image or to CD - check the required plugins are enabled or not.
You might want to give a look at DPsBase if you not yet created a SATA plugin for MEE.
The above only works for BartPE, not for WinPE so be warned. Adding drivers to an AIK created WinPE cd is now pretty easy - see my script on CTOGoneWild as above for inspiration, but basically you just run
peimg /inf="driver inf file name" "mount point of the Windows directory of your mounted WinPE creation"
see the peimg command help for full details.
is there any guide on making wintech on winpe? i only have the one with bartpe.
Is anyone trying reatogo (based on BartPe) - it has neat feature to autodetect your driver
Yes, there's an overview, you can get it I think though ONLY through Platinum support. It's not published on the standard CDs at the moment. If I am wrong though please someone let me know where the public version is.
The BartPE guide does explain what you have to do though, though not how to do it as there are so many versions of WinPE - for the latest version (AIK) just use the script from google.com/site/ctogonewild
