A. Its possible to configure extra files for an installation that might be specific to your organization or to the hardware in the machine. These are placed under the $OEM$ directory of the I386 structure and under $OEM$ you can have the following:

\$OEM$\textmode Hardware dependant files for use during the initial Windows 2000 install and text mode setup such as OEM HAL's, SCSI drivers etc.
\$OEM$\$$ Used to replace any core system files and must match the structure of the Winnt structure. For example to replace files in the winnt\system32 directory you would create \$OEM$\$$\system32
\$OEM$\$1 Files that you want to be copied to the drive where Windows 2000 is installed (%systemroot%)
\$OEM$\ Same as $1 but allows you to set a specific drive letter, e.g. \$OEM$\C would copy everything under it (including subdirectories) to C
