I tryed to add som nic drivers to my PE structure before I made the iso..
I have not succeed I have tryed to put support for Intel PRO/1000 MT (E1000NT5.SYS) (Dell drv R66787).. for Optiplex GX270..

I put the files like
Copy the drivers (*.inf) to c:\mywinpe\i386\inf
Copy the drivers (*.exe, *.dll and *.din) to c:\mywinpe\i386\system32
Copy the drivers (*.sys, *.bin, *.pat) to c:\mywinpe\i386\system32\drivers

I put the files intelnic.dll, net8254x.din, e1000nt5.sys prounstl.exe, e1000msg.dll, E1000325.inf..like above.

I have tried the BartPE with a nic plugin and before I made the iso i coppied newer drivers for the nic like above in to the BartPE structure....
wolla It booted......

I use PE 1.2 (OEM win XP SP1 swedish )with Win server 2003 (US) files

Per

Make sure your WINBOM.INI has the following.....
[PnPDrivers]
CDROM:\ = D:\I386\INF
CDROM:\ = D:\I386\SYSTEM32\DRIVERS
CDROM:\ = D:\I386\SYSTEM32

Also edit your startnet.cmd so that factory starts in WINPE mode
it should look like this,

@regsvr32 /s netcfgx.dll
factory -winpe
netcfg -v winpe

That should get you up and running.

Thanks Crowgoth!!

Now it works with nic support for GX270......
Well I have also mixed up the drivers
I checked witch drivers XP use, and I found E1000325.sys well I found
on Dell support cd the e1000nt5.sys and in some docs.. I looked in the readme file it seams to be to precision 360, I checked a P360 XP PC and fount E1000325.sys.... So I put all files for E1000325.sys and e1000nt5.sys in there places then It PE booted with nic support..

Thanks again
bye Per
