Hi Andrew Bobulsky,<BR>

<BR>
I don't think it need a second iSCSI connection if you put more than one LUNs to one target, most of popular iscsi initiators suppport multiple-lun feature, all the luns use only one connection.<BR>
I think at least two things we need to do:<BR>
1, Modify int13 interrupt in gpxe and make it support CD-ROM.<BR>
2, Make target support multiple-lun.<BR>
<BR>
Windows setup will start to boot from gpxe (A iSCSI target with hold a CD-ROM and a harddisk is already descried by ibft), and then press F6 to install a third-party iSCSI drivers.<BR>
The iSCSI drivers will prepare two devices for windows (a hard drive and a CD-ROM).<BR>
<BR>
>By the way, is your target OS here XP/2003 setup?<BR>
Yes, I only consider windows at this time.<BR>

<DIV>While I read that and though it might be a clever solution, the string that you pass to the sanboot command includes the LUN you want to connect the int13 device to, which defaults to LUN 0.</DIV>

<DIV>So, if you were to put an iSCSI HDD on LUN 0 and an iSCSI ODD on LUN 1, you'd still need to specify a second iSCSI connection :-(</DIV>

<DIV>By the way, is your target OS here XP/2003 setup?</DIV>
