Hi all! Apologies if i've posted in the wrong forum: am not sure whether to use the device driver forum or the unattended RIS install forum. I'm having an issue with the preparing a RIS installation of Windows XP Professional. I've created an unattended install, and when I do a RIS deployment on Dell Optiplex GX520 machines with Broadcom 57xx network cards. I get 2 sorts of error messages: 1) STOP message during text-mode setup An initialization failure occured while attempting to boot from network. 0x000000BB(0x00000003, 0xc00000BD, 0x00000000, 0x00000000) 2) 'Unexpected Error' message after 'Starting Windows...' during text-mode setup File b57w2k.sys caused an unexpected error (21) at line 3788 in d:\xpsprtm\base\boot\setup\setup.c. Press any key to continue. The files concerned are b57w2k.sys b57win32.inf b57xp32.sys I have two questions: The person in this post talks about 'reverting' to Win2k drivers. How is this done? I've attempted copying the b57w2k.sys (and the .inf file) to the i386 folder (and doing a restart of the BINL service), but I get the STOP error message. Updated drivers for the Broadcomm 57xx integrated NIC's are available from both Dell and Broadcom. Which drivers should I download, and which OS drivers should I integrate into the i386 folder (Win2k or WinXP)? Any input on this situation would be greatly appreciated. Thanks.
