-==== Displaying the boot driver list ====+  * Norton Internet Security'​s (at least 2009 and 2010) firewall is known to cause boot-time problems on XP.  Disable the firewall before transferring your disk image to the iSCSI server.

 +===== VMware-specific problems ===== 
 + 
 +VMware has a nasty habit of changing the PCI bus:dev.fn number assigned to the virtual NIC, which breaks the Windows driver bindings and so prevents a successful iSCSI boot.  In most cases, you should ensure that the ''​.vmx''​ file for the VM that you are attempting to boot via iSCSI contains 
 + 
 +    scsi0.present = "​TRUE"​ 
 + 
 +even though there is no local hard disk attached.((VMware seems to assign PCI bus:dev.fn numbers dynamically. ​ If you have a hard disk and a NIC in your virtual machine then VMware will typically assign the hard disk controller as PCI device 00:10.0 and the NIC as PCI device 00:​11.0. ​ You perform the Windows installation within the virtual machine then detach the hard disk, transfer the contents of the virtual hard disk to your iSCSI target, and try to boot from it.  VMware will now reassign the NIC as PCI device 00:10.0, which will prevent Windows from enumerating the NIC correctly. ​ By setting 
 + 
 +    scsi0.present="​TRUE"​ 
 + 
 +you can force VMware to create a hard disk controller (with no disks attached) as PCI device 00:10.0 and so reassign the NIC as PCI device 00:11.0, which is where Windows expects to find it.))
