I know this information exists elsewhere in the world and I really dislike redundant posts. But I’m always hard-pressed to find this so am posting it here more as a reminder to myself. If it is of use to anyone else, all the better.
When you update a MDT 2010 Update 1 distribution share that includes the option to create a bootable ISO, the OSCDIMG command (in RunCmd.cmd), as well as a log of the output (PEManager.log), is located at %Temp%\PEManager.####, for example, C:\Users\Aaron\AppData\Local\Temp\PEManager.4336.
“C:\Program Files\Windows AIK\Tools\AMD64\OSCDIMG.EXE”
-yo”C:\Program Files\Microsoft Deployment Toolkit\Templates\BootOrder.txt”
-bootdata:2#p0,e,b”C:\Program Files\Windows AIK\Tools\PETools\amd64\boot\ETFSBOOT.COM”#pEF,e,b”C:\Program Files\Windows AIK\Tools\PETools\amd64\boot\EFISYS.BIN”
> “C:\Users\Aaron\AppData\Local\Temp\PEManager.4336\PEManager.log” 2>&1
See [some website] for details on the various OSCDIMG parameters.
