Hi, I'm attempting to netboot Linux on my Macs. I don't want to mess around with boot cds, so I have to maket his work with the Macs EFI firmware.
The first problem I encountered with iPXE is that I don't see any output on the screen. That's because Macs start in graphic mode. The attached hack(inspired by Refit's textmode.efi) puts the firmware into text mode, so I actually see something. The next problem(for debugging purposes), is that Ctrl-B does not work. I replaced the key with 'a', which allows me to bring up the iPXE shell. The next issue is that iPXE doesn't find my network card. This seems to be a regression, because it works fine with gPXE(I just filed to gPXE bugs before I noticed that iPXE exists now). I tried the following builds: make bin-i386-efi/ipxe.efi make bin-i386-efi/sky2.efi make bin-i386-efi/sky2.efi DEBUG=sky2 None of them works. If I don't open the console, I see "o more network devices" (with an o, not a 0). Currently I've netboot working by loading a grub2 .efi file with a memdisk image that contains a config file and kernel. I hope to replace this with a solution that allows me to separate the boot loader, kernel and configuration. Best regards, Stefan
