similar to: [Patch]: Drive/Partition and extensible filesystem support for syslinux

This is a continuation to the library creation effort for syslinux. I added the necessary ops required to read partitions and sectors off the disk. I'm using it with my com32 module. I did change the interface for read_disk a bit, so it takes a disk_info argument. This way I can maintain multiple instances of read handlers, for example if I'm reading and comparing stuff from two different

git://gnx.ath.cx/syslinux.git On branch for_hpa, I've got several groups of changes (listed bottom up) -chain.c32: the beginning of a DRMK loader; I still need to test this further and document/code what ones can possibly work -mtools/syslinux.c: Check to be sure fs is not NULL in case libfat_open() failed, like it can on a bad filesystem. Try to present a useful error rather than a seg

This patch will improve the flow at disk_write_sectors and disk_read_sectors significantly, but it *will* introduce bugs if either of the above functions gets called before disk_get_params. --- com32/include/syslinux/disk.h | 21 +++++ com32/lib/syslinux/disk.c | 170 +++++++++++++++++++++-------------------- 2 files changed, 108 insertions(+), 83 deletions(-) diff --git

This patch will improve the flow at disk_write_sectors and disk_read_sectors. It does that by creating a table of values respective to the operation. Besides, read and write operations are pretty similar to each other, so I redesigned the routines to avoid duplication.

eparam will only be used if EBIOS is available on the underlying disk.

Hi list! Sometimes I need to make boot floppies for an i386 based Linux router. Just for interest, I tried to use syslinux together with my iMac G4 (PPC) with Yellow Dog Linux to create the floppy. I know that this is generally difficult because it requires cross- compiler and cross-assembler. Nevertheless, I tried it because I only needed the disk installer, the loader binaries for i386

I just tried to build syslinux-3.71-pre14-5-gfa6a60e and got the following: make[1]: Leaving directory `/syslinux/syslinux-3.71-pre14-5-gfa6a60e/dos' make[1]: find-mingw.sh: Command not found make[1]: Entering directory `/syslinux/syslinux-3.71-pre14-5-gfa6a60e/win32' gcc -Wp,-MT,syslinux.o,-MMD,.syslinux.o.d -W -Wall -Wno-sign-compare -Os -fomit-frame-pointer -D_FILE_OFFSET_BITS=64 -I.

libfat and libinstaller compile fine using the Windows Driver Kit's compiler, except for a few warnings that are addressed with this patch.

In my last post I pasted the last few line of the compile log for syslinux-3.02pre2. Here are the correct lines from my failed attempt to compile syslinux-3.01. Still the same error. make[1]: Leaving directory `/usr/src/syslinux-3.01/unix' make[1]: Entering directory `/usr/src/syslinux-3.01/extlinux' gcc -Wp,-MT,extlinux.o,-MMD,.extlinux.o.d -W -Wall -Wno-sign-compare

Hello all, apologies if my question has an obvious answer or it's too naive (I sent this directly to Peter with the intent of not chocking the list with possibly ridicolous questions...). I just tried to build both syslinux-3.00 and 3.01, with the same bad result. Out of the box compilation with: make depend make installer fails with: ... gcc -Wp,-MT,extlinux.o,-MMD,.extlinux.o.d -W

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

Pulled common code out of these functions into new ones. The functions chs_setup and ebios_setup were created for this purpose.

The variable 'ok' is never used and generates a warning. Remove it. Also ntfssect.c is designed to be compiled in non Unicode mode when using MSVC compilers, so remove all ambiguity about it (LPCTSTR -> LPCSTR, use of 'A' API calls) so that it doesn't break when compiled in Unicode mode, which is what Rufus uses with MSVC. -------------- next part --------------

It has been observed that binaries contents are depending on the order of linked objects. This order is caused by GNU make's wildcard function and the position of sources on filesystem. This change tries to prevent this kind of randomness. Also consider building using -j1 flag to make it even more reproductible. Change-Id: Ie8eee7f336e6f1fa2863c4150d967afd15519f1d Bug:

Previous version had some issues in case of error situations, among those: - backup gpt header was not read if reading of primary failed - alternating nature of lba_cur and lba_alt was ignored This patch fixes this and extends the gpt handling. The current behavior is: - try primary header; if unreadable or checksum fails (or sanity checks fail unless relax flag is set) - try secondary header

This is a bit updated set of chain.c32 changes that simplifies a few things (and in partiter part), fixes few minor issues and adds a few new features. Details are in the following commits, below is the summary and pull details at the end. Shao - any chance to peek over them ? Most of those are relatively simple changes and well tested, though of course something might have slipped my attention.
