...fetches key sectors of the image to visually verify this info. Now, I'm thinking that if it doesn't smell/taste the same as SYSLINUX on FAT*, it's not a valid test as BIOSs commonly use the first sector to guess the intended geometry. I'm copying (for now) the boot sector code from diskstart.inc. Now, nasm is acting like the PartInfo sub-constants (for lack of better/proper terminology) are local labels. I'm guessing it's either bad syntax in diskstart.inc or a parser-related bug in nasm. I'm working around this (for now) by having a label just before these constants. T...

git://git.zytor.com/users/genec/syslinux.git Branch core-diskstart-boot-for-hpa. I found that INT 13h AH 08h in BOCHS used ES, DI, at least when using a partitionless HDD, causing "Boot error" from the magic check as it was loaded to the wrong location. HPA suggested wrapping INT 13h with the push/pop for ES's safety. This then lead to checking ov...

Hi Feng, I'm currently hitting the overflow in core/diskstart.inc on the elfink branch where I see you changed the overflow check, commit 2e91ec5f155f04aee878ed70a04fb5b15e40da3b Author: Feng Tang <feng.tang at intel.com> Date: Wed Jul 14 15:55:25 2010 +0800 elflink: a lot of core/fs merge @@ -691,16 +798,22 @@ rl_checkpt equ $...

git://git.zytor.com/users/genec/syslinux.git Branch core-diskstart-chkerr-for-hpa verify_checksum is built to allow for segment wrap (ldlinux.sys larger than 33280 bytes if my math is right). If the wrap occurs, DS is no longer 0. If there's a checksum error after DS is no longer 0, it won't be able print checksumerr_msg properly. 2 commits: 1 to make...

After so much time and improvements, I'm glad to see and publicize a pre-release, 6.04-pre1 in https://www.kernel.org/pub/linux/utils/boot/syslinux/Testing/6.04/ Personally, I've already been working testing the pre-release as-is and my tests have been positive so far. I appreciate feedback like that from Gabriele Balducci and testing "make bios installer". Yes, there are a

I need to debug some issue in second stage of syslinux boot, i.e. ldlinux.sys. I have put a few debug instructions in core/diskstart.inc and recompiled everything. The newly obtained ldlinux.sys confirms to the size restriction for the boot sector. Now how do o replace the current /boot/ldlinux.sys file with mine. I tried removing the immutable flag and then doing a copy. Nothing changes. It still loads the old one. If i delete...

I will have to dig in and see how this all gets compiled (pointers always appreciated :-) ). An install on Linux (before I run "syslinux --install") actually doesn't have ldlinux.sys or ldlinux.bin anywhere. Are they embedded into the syslinux binary and it installs bytes, vs co...

...n the list. The list is also expanded to complete the permutations. Branch handoff_mbr_for_hpa introduced a new MBR/VBR to show the handoff parameters. HPA: Should this be moved to diag/ (I'm putting my geometry display code in a subdirectory there; still prepping for a branch)? Branch core-diskstart-chkerr-for-hpa fixes DS in the (future) situation that copying ldlinux.sys results in DS not being 0. Segment 0 contains the error message string we need in case of failure and DS !=0 would prevent this error message from properly displaying. Branch diskboot-comment-for-hpa adds some comments to...
