When the Dell driver for the Broadcom NetXtreme Family of Adapters, v16.2.0, A01 is installed, the OS gets stuck in a continuous loop on a BXOIS.SYS error. In my case this occurred on the 5708 series Broadcom. I was able to reproduce this in our development and QA environments. The solution is to boot to the Windows Recovery Console and load a command prompt. Then manually delete the offending file (bxois.sys) from %windir%/drivers. This will allow you to once again boot into the OS at which point you must reinstall your network drivers manually. Link to the offending driver is here: http://ftp.dell.com/network/NIC_DRVR_WIN_R297264.EXE The drivers you need to replace this with can be had here: http://www.broadcom.com/support/ethernet_nic/netxtremeii.php I will report this to Dell as well.
