OSD - Memory Management issues with Dell 1950

When trying to install a Dell 1950 with OSD (DOS Based setup), you may run into issues with the DOS Memeory Management. The build in SAS Raid Controller allocates memory areas that are also allocated by the emm386 under DOS.

The behavior we observed was that the harddrive was partitioned and fromatted properly (first 2 pxe boots), but when we tried to run the third boot to initiate the actual setup ... the harddrive was no longer available.

"Error accesing Drive C:"

An easy solution for the problem was to get rid of the emm386 entry in the config.sys (hidden inthe setup.px archive).
