I ran into this problem as well and the "rarp" "root (nd)" suggestion got me past that. However, once the multiboot loaded, and the custom jumpstart began I kept getting rpcbind failures trying to connect to the jumpstart server. This is odd since this is also the boot server, and it found the multiboot there just fine (confirmed via snoop).
The error looked exactly like Bug ID: 6617920 (http://bugs.opensolaris.org/view_bug.do;jsessionid=24b24f48a238b90f34ceeeb1544?bug_id=6617920) The only difference is - We're not using DHCP. When the process exited to the shell, I DID have the correct IP address, but the default netmask (255.255.255.0), which doesn't work in our environment. I eventually resolved this by combining the two suggestions above. I manually edited the grub menu to the following and it worked without a hitch. rarp root (nd) ifconfig --mask=255.255.0.0 kernel /I86PC.Solaris_10-1/multiboot kernel/unix -B install_media=<myIPaddress>:/export/jumpstart/sol_10_x86/install,install_boot=<myIPaddress>:/export/jumpstart/sol_10_x86/install/boot - install module /I86PC.Solaris_10-1/x86.miniroot Thanks for the suggestions ( dminer & koppenho) and hopefully this will help someone else.
