Background: We have been struggling to find the correct fix to a problem with the Boot media on a T61 with the SATA drives set to AHCI mode. The WinPE would fail only (only!) on the T61 in AHCI mode, but work for every other computer model - even newer ones in AHCI mode. It would not see the drive enough to even start the Partitioning process.
OK, that being said, we think we finally got the right drivers in the WinPE image, and when we create the boot media it works for the ISO/boot CD media.
It does NOT work when we create the USB media at the same time! Seems the media have different drivers?
