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(+)...

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. Signed-off-by: Raphael S.Carvalho <raphael.scarv at gmail.com> --- com32/i...

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.

Hello, the following patches should get multidisk access working. The syntax accepted is the following: (hdx,y)/path/to/file where x is the disk number and start at 0 and the y is the partition number starting at 1. So (hd0,1) is the first partition of the first disk. the other accepted syntax is using MBR's 32 bits disk signature so for example: (mbr:0x12345678,2)/foo/bar would address
