The Start.cmd is simply a routine instigated in the winnt.sif ([GuiRunOnce]) to go to the Install/network folder and execute the setup.exe for the NIC driver. This driver seems not to be available in OEM format and won't install if included in the OEMdrivers path in the winnt.sif. The IE6 installs at the end of the XP installation routine. This happens whether or not the start.cmd is in the winnt.sif. The IE6 install is not an issue; it is the timing of the IE6 or the start.cmd routine that is a problem. As I said before it actually does not make any difference to the end result because the start.cmd allows 1 minute before is reboots the machine, which is enough time for the XP install to finish installing the IE6. see below for start.cmd contents. ******************************************************************* CLS @echo off TITLE Windows XP SP3 - Unattended Installation ECHO.
