The following boot entries: # COM32 chain.c32 APPEND fs ntldr=/bootmgr # or: # COM32 chain.c32 APPEND hd0,1 ntldr=/bootmgr # might result in the following error: # Insane primary (MBR) partition. Can't find myself on the drive I booted from. # when using chain.c32 v4.07. I have seen similar error reports when using chain.c32 v4.06 too. It works correctly with chain.c32 v4.05, even when

I just tested 6.02-pre10 version. ? On physsical machine it is booting ok now,?but chain.c32 result is the same errors :? ERR: Primary partition (in MBR) with invalid offset and/or length. ? ERR: Cant't find myself on the drive I booted from Adding 'relax' option to chain.c32 invocation resolves the problem. ? In qemu the boot and chaining works ok (without 'relax' option).

Hello syslinux list, I have installed Arch over a btrfs-formatted dos/MBR primary partition* (no btrfs subvolumes, just installing everything including /boot in the root of the btrfs). I have been unsuccessful for several days trying to get it to boot with syslinux (6.02-8 package from Arch, also tried 4.07-1 Arch package). All I am getting is the copyright header line and a blinking cursor

Yes. Prior versions (all to 6.01 inclusive) are working very well. ?And yes it fail before invoking chain.c32 (as I said in qemu there is no errors). ________________________________ From: Matt Fleming <matt at console-pimps.org> To: Adrian Irimia <adixtx at yahoo.com> Cc: "syslinux at zytor.com" <syslinux at zytor.com> Sent: Tuesday, July 23, 2013 5:16 PM

This small set fixes few bugs, improves gpt handling (under buggy conditions) and implements strict flag with more fine grained control which should fix issues with sanity checks against disk sizes. If this set is allright I'd want to do what I mentioned in older discussion with Ady - backport missing patches from 6.x to 5.x and 4.x so all versions have up to date chain version. Michal

Grub Legacy stage2 will read the install_partition variable from memory address 0x8208. We only need to change the value at 0x820a to the correct partition number: -1: whole drive (default) 0-3: primary partitions 4-*: logical partitions Signed-off-by: Gert Hulselmans <gerth at zytor.com> --- com32/modules/chain.c | 13 ++++++++----- 1 files changed, 8 insertions(+), 5

Hello Gene, thanks for your reply. Yes BIOS mode. The config wants a menu, which loads fine under ext4 and not under btrfs. Under btrfs I have also tried to remove the syslinux.cfg file altogether (which should trigger the boot: prompt if I am not mistaken) and the result is the same: only the copyright line appears and no prompt. The three letter sequence is EDD. The disk is 160GB, here is the
