Windows 8 iSCSi Boot - INACCESSIBLE_BOOT_DEVICE

[Football24]

We are trying to boot Windows 8 from an iSCSI target. I have an i7 based diskless client. I used its PXE ROM to boot iPXE according to these steps:
http://ipxe.org/howto/msdhcp#pxe_chainloading

After iPXE loads I use a .ipxe script on my Web Server to have wimboot run and I can connect to and install Windows 8 (after patching my NIC driver into boot.wim and install.wim) to my iSCSi target as outlined here:
http://ipxe.org/wimboot

After Windows 8 installation to my iSCSI target my PXE rom boots iPXE, connects to the iSCSI SAN, then proceeds to boot Windows 8 from my iSCSI target. Just before I get to screen where I would expect Windows to ask my the final questions about users and computer name I get what appears to be a BSOD with INACCESSIBLE_BOOT_DEVICE (Your PC ran into a problem and needs to restart. If you'd like to know more,you can search online later for this error: INACCESSIBLE_BOOT_DEVICE).

Can somebody PLEASE tell me what I might need to do? Do I need to somehow get some iSCSI initiator drivers into my Windows 8 install.wim image?

Thanks,
Todd
