After commit 036fa4e1a8aefeba3, shouldn't bsCodeLen be adjusted to reflect added fields at the end ? Basically: -#define bsCodeLen (offsetof(struct boot_sector, bsSignature) - \ +#define bsCodeLen (offsetof(struct boot_sector, bsMagic) - \

...because at the moment, it is not known what the default drive is??). Well, in any case, I would really appreciate if someone can let me know if what I want to do is possible at all with syslinux; and possibly how to do it...

The commit to isohdpfx.S of 2009-05-31 looks incomplete. The sequence of the stack pointers was swapped, but the sequence of stack pushes was not.

When call isohybrid with option '-u', it overflows on a 32 bits host. It seeks to 512 bytes before the end of the image to install gpt header. If the size of image is larger than LONG_MAX, it overflows fseek() and cause error: isohybrid: wrlinux-image-x86-64-20140505110100.iso: seek error - 8: Invalid argument Check the offset and call fseek() multi-times if offset is too large.

...... This error message stems from isolinux.bin, not from the MBR. So we really ended up in the running boot image program. The checksum is tested with all isolinux.bin starts. From CD too. It belongs to the Boot Info Table feature inside isolinux.bin (see "man mkisofs" or libisofs-*/doc/boot_sectors.txt): Byte Range | Value | Meaning ---------- | ---------- | ---------------------------------------------------- 8 - 11 | pvd_lba | Block address of the Primary Volume Descriptor. | | This is the session start LBA + 16. | | 12 - 15 | f...

Open question is whether the fix helps with David's BIOS. The newest answer from Martin indicates that a failure to read

This set of patches add some support for sector size >512. Currently it fixes extlinux, MBR for GPT and ext partitions. Other code is unaffected. This set of patches has been tested on a read Dell machine running a beta firmware.

Hi, i now realized that http://www.syslinux.org/wiki/index.php/Hardware_Compatibility#USB-Geometry http://www.syslinux.org/wiki/index.php/Hardware_Compatibility#USB-Miscellaneous are the new wiki sections by Gene Cumm. (Sorry for not reading them when they were announced.) So i ask especially him whether the statement "An examle is a drive of 128,64,32 with a partition ending at
