Various EFI systems insist that there be no active flag in the pMBR in order to parse the GPT. The only way around this is to also generate a valid MBR - the firmware will then pick that up and use the system partition provided there. In order to deal with other EFI "sanity" checks, the partition type for the non-EFI partitions is set to 0 to skip the fir...

Hi, if I inspect an hybrid ISO with tools like fdisk and gdisk, then looks like hybrid ISO has both the MBR and GPT in order to support both the BIOS and UEFI: # gdisk -l /dev/sdb GPT fdisk (gdisk) version 0.8.10 Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: present Found valid MBR and GPT. Which do you want to use? 1 - MBR 2 - GPT 3 - Create blank GPT Your ans...

Hi, Is it possible to always load syslinux from whichever partition it?s installed on, regardless of whether it?s active or not (and even if it?s a logical partition), just like grub? The MBR code that ships with syslinux (much like dos/windows default MBR) would only boot the active primary partition. It would be nice if you could provide a custom MBR such that one could set one byte in the MBR indicating which partition should be booted (0,1,2,3 for primary/extended and 4,5,6,? for lo...

Hello, I'm trying to install FreeBSD 9.1 amd64 on an IBM x3550 M3 server. Installation went smoothly, RAID controller and network cards were successfully recognised. But, after the installation, the server fails to boot from disk. There were some posts, about two years ago, in this list implying that the problem lies in UEFI but I couldn't find any clear solution. Any suggestions would

This patches add support for dynamic sectors to GPT MBR code. First 3 patches are trick and optimizations to gain some space for the forth patch. I have a modified version of SeaBIOS, some code and some script o test it I'll send on a different mail.
