Unable to boot http ISO files using SANBOOT

[robinsmidsrod]

Sanboot using HTTP and an ISO file works in the same way as memdisk, except the file is loaded in chunks into memory as needed. This requires your web server to support ranged requests. Apache does this in the default install on most distros. Sanboot itself doesn't require iSCSI, when used like this.

My guess is that the ERD tool is not loaded totally in memory, but tries to access the CD after it has booted. In that case, you need to figure out how to tell it to look for its information somewhere on the network, because the virtual CDROM is not available. If it is just a plain boot.wim file inside the ISO that is running a WinPE system then you should be able to boot it using wimboot, see http://ipxe.org/wimboot for details.
