[arch-releng] [PATCH] [archiso] Workaround broken BIOS for ISOLINUX
Avoiding different issues like instant reboot or error messages.
This ensure that isolinux.bin is located on the most low extent possible (LBA 34) just after boot.cat (LBA 33).

OK, finally found the offending commit after many many tests[#1] burning differents ISOs.

I don't think we rebuild the asm code in our syslinux package, as upstream doesn't recommend it. Instead, we only build the syslinux installer and use the shipped binaries.

Oh, it seems that was reverted. So this should work fine.

Yes. Can be great if the new pkg goes to [core] before next 2013.12 ;)
Thanks

You can fix the package yourself and put it to [testing].

You had permissions to do that all along.
