[syslinux] gfxboot again - EFI64

[Andreas Heinlein]

Hello,

I think I found another problem with gfxboot, and I think it is 
completely unrelated to the 'packed archive' issue.

Again I tried using gfxboot with the Ubuntu gfxboot archive, this time 
with EFI64, using a real EFI-capable machine. I first verified that 
everything else actually works by commenting out 'ui gfxboot bootlogo' 
and got a working menu. Uncommented the line again, and the screen goes 
black immediately, no output at all. This time it's also really not 
working, no 'blind' typing possible, default entry will not boot after 
timeout.

The same with a minimal config. I must say that I used a USB drive 
instead of a DVD this time, for convenience. And I'm not sure if I got 
the file layout right. It had a GPT table with a single FAT32 partition. 
I copied syslinux.efi to \EFI\BOOT\BOOTx64.efi; ldlinux.e64 to 
\ldlinux.sys and everything else (syslinux.cfg, gfxboot archive, *.c32 
files from efi64/com32) to \boot\syslinux\.
But since the vesamenu worked, I think this is correct.

Just to be sure, I also tested with an unpacked gfxboot archive, but 
again nothing.

Any ideas?

Thanks,
Andreas

P.S.: While I'm typing this, I can see that the test machine eventually 
reboots after 2 or 3 minutes of black screen - no idea if this helps.
