Hi,
I had the same problem with ERD 5.0 (now MS DART).
For the net drivers, I needed to go one by one.. and I couldn't use driverpacks for some reason. After a point, I just got a looping error that I couldn't avoid. I think its because there were too many drivers. I used UBCD4win's abridged set of net drivers... I still had to add 1 by 1, but microsoft's interface didn't crash when all was said and done (I did get some errors though).
As far as the mass storage driver goes, this is a bit tricky.
1) Firstly, you need to make a valid ERD iso, with the net drivers included. Go through the whole process, just don't burn the ISO to the CD.
2) Once you have done this, use an ISO utility to extract the entire ISO to a directory.
3) The ERD is really a winpe environment (sort of), but for some reason the driverpacks base does not realize its a valid set of files. We need to trick the driverpacks base installer to continue. What I did was I copied the contents of the I386 directory FROM A WINDOWS CD into the I386 directory of our extracted ISO.
4) At this point, the driverpack's installer will let you select bartpe as the installation type and continue. Continue to the next step, but don't go any further.
5) Now, we must delete the I386 directory (since we dumped all the CD files in there) and re-extract the I386 directory from ISO we made in step 1.
Basically all the steps now have simply been to trick driverpacks into letting us move forward with a standard slipstream. In our directory, our contents should still be identical to that ERD ISO we made in step 1.
6) Select the txtsetup method to install the mass storage files. This is what you need since ERD is like a bartpe environment.
7) Finish the driverpacks setup, and let it slipstream.
At this point ,we have all we need. The ERD has been updated, and the drivers are slipstream. We still need to make the CD, but many people might not know how to extract the boot image from the ERD ISO. There is an easy way to get around this:
1)Start an other ERD install, but get up until the point where it shows you the temporary directory (and you have the option to browse.
2) Click on browse, and delete the entire contents of this directory.
3) Open up the folder we have been working with (the extracted ISO directory, which should now be slipstreamed with the mass storage drivers). COPY the contents of this folder into the ERD temp directory.
In essence, we just replaced all of the preloaded MSFT ERD files with our slipstreamed version of ERD. All the ERD disc setup does from here is copy over some executables, so nothing important is overwritten.
I was unsure whether this would work or not, but appears to have been successful. I'm still a little unsure of what help the net drivers are, launching a browser doesn't seem to work.
I would really rather use these tools within a bartPE disc, but this version doesn't appear to work correctly. I would love to see a plugin if anyone has access to it..
