[gPXE] Try another boot-image on iSCSI boot failure

[ewheeler]

Hello,

I've read most of the wiki to see if this is possible and have not seen
any hints in this direction:

When installing Windows  7 on an iSCSI device, Windows7 must see an
iSCSI device in the iBFT to know that the device is bootable to present
it as a bootable (thus installable) medium.

I would like to have gPXE configure the iBFT for the iSCSI device I wish
to boot from, using gpxe.keep-san=1 to keep it resident, and then chain
to yet-another-bootloader that will launch the Windows 7 installer.  

One site suggests netbooting gPXE with keep-san=1 and when it fails
booting from the virgin iSCSI disk, let the system BIOS boot the Windows
7 install CD as the next boot attempt.  The problem here is that /my/
BIOS will not try another boot image after the first one fails. 

Is there a way to do this?

Any help would be greatly appreciated.   Thanks!

-Eric
