[gPXE] Will gPXE support booting from iscsi cd-rom?

[KernSafe Technology]

Hi all,

 

I'd also interest in this topic, if we modify int13 and implement a CD-ROM, when windows installation startup, press F6 to install a iSCSI initiator driver, is it will possible to install a OS by using a virtual CDROM in a SAN? 
It will be more convince for users, because some type of SANs (as we have) have a virtual CD-ROM emulator function, so the workstations do not require a physical disk installed and not require a CD-ROM either.

> gPXE can support booting an iSCSI HDD with GRUB4DOS installed on it. If you put an .ISO image on a partition in that SAN, then you can:
