Idea behind changing the drive letter:
In order to access DS share (express deployment share) in automation environment we map a drive while creating PXE image through BDC. [ Step 6 of 12 : Network drive mapping] .
By default PXE maps express drive to letter F:
But the real problem occurs in automation when source computer have multiple partition say C,D and E.
In automation C becomes D, D becomes E and E becomes F.
As F letter id already allocated in automation PXE failed to map deployment share to F:
and hence it will show prompt X: ....................[ means fail to map depoyment share]
otherwise it will shows prompt F: ....................[ mean ssuccessfully mapped depoyment share]
What does changing the mappath to 7 do?
As i have mentioned in previous answer that "By default PXE maps express drive to letter F: ".
It is mentioned in default.cfg file by setting mappath0=\\Deployment-server-name\Express.
Here mappath0 means F:
If we change this to mappath7=\\Deployment-server-name\Express
Here mappath7 means M:
This is just to map drive to letter which is higher that F
Let me know if you need more information.
