Nice job figuring this out and getting gPXE to boot OpenSolaris! Syslinux mboot.c32 supports Solaris so I have CCed H. Peter Anvin who might have some ideas and has solved GRUB and Solaris multiboot quirks for Syslinux. > - Opensolaris expects to receive the full path to the kernel, not just the > filename. Do you have a link to the code? Depending on how the image command line is parsed it may be possible to satisfy Solaris without forcing the image command-line to start with "/platform/i86pc/kernel/unix". Maybe ;). > - Grub loads modules at the beginning of the address space, while Gpxe seems > to do at the end. > Opensolaris's kernel startup routine expects grub's behavior, and searches for > a region of free memory after the address of the last loaded module, which is > normally not available when you use gpxe. Do you have a link to the code? Any idea what the minimum free memory requirement is? We can't hardcode urealloc(UNULL, 255*1024*1024) since multiboot should work on machines with 256 MB or less. > - Opensolaris expects to be passed the DHCP ACK packet. This quirk disregards the multiboot specification by replacing what would normally be a drive description with a DHCP packet. This means gPXE cannot unconditionally fill the DHCP packet in since non-Solaris images might try to interpret this information as a drive. The Solaris kernel either needs to be recognized automatically by gPXE or a setting is needed to control this variation from the multiboot specification. Any ideas on recognizing a Solaris kernel? If there is no simple unique way to identify a Solaris kernel image then a settings variable could be used. > Perhaps someone more familiar with the gpxe codebase, can take a look at it > and transform it into a proper patch. Thanks for your efforts. I think some discussion and refinement of your patch will lead to Solaris boot support in mainline gPXE, so I hope you are interested in taking this patch further :).
