how to install AMT SOL/LMS and HECI drivers silently

[dding0919]

I'm trying to use a batch program to install AMT SOL/LMS and HECI silently on our new Dell Optiplex 755. Following is my code. I downloaded the software from Dell website. Chipset1 is for chipset software installation utility and it seems working fine. When it ran it took about 10-15 seconds. But the other two will exit in a couple seconds though no errors logged. Any idea how to do it?

I got it fixed. For some reason the start/wait is the cause. I have it removed and just set to setup.exe -s for all of them. And it worked. For SOL/LMS and HECI setup.exe -? will show you all the switches. I don't know why start/wait won't work. Usually that's what you need to use in a batch program so it won't run next command till it completes current external program.
