I am glad to say that somehow or rather, I manage to install BartPE into a USB flash drive and successfully run LAN connection and wireless connection to the internet on my Toshiba notebook. Besides the usual plugins that came along with pebuilder3110a, I added the xpe-1.0.7 and wireless service plugins into the compilation.
For the ramdisk.inf, I tried to use RamDiskDiskSize="0x08000000" which said that the size should be 128 MB, but when BartPE is working, I can only get around 95 MB as drive B:.
While surfing the net I downloaded and installed the warez 12 bootcd and found that the mini Windows XP there can give a B: ramdisk of 823 MB on my motherboard that had 2 GB of RAM installed.
I shall be very glad if anyone can tell me how to do this with the BartPE pebuilder3110a program.
Thanks again for everyones' help and information posted in this wonderful forum.
