This patch introduces extra functionality to chain.c, mainly with reference to BPB adjustments, but not only that. It expects 3 small patches I sent earlier (they are included for easy reference, patches 1-3/4). The changes introduced are: 1) file and boot sector use separate options to control load address and jump address (if applicable). Options are as described below: *

Usage is like this: #include <syslinux/io.h> #include <syslinux/partitions.h> #include <fs/fat/libfat.h> syslinux_devdesc dfd; struct libfat_filesystem* fs; diskinfo disk_info; char mbr[512]; static part_entry *partition; int fd; syslinux_get_disk_params(drive, &disk_info); // specify your drive number syslinux_read_disk(&disk_info, mbr, 0, 1); // Read mbr partition = PARTITION_ENTRY(mbr, 2); // 2 for partition 2 // this is the disk device/partition descriptor dfd.disk_info = &disk_info; df...

...tions, etc. There was some discussion on whether the FAT library, should be in com32/lib, but its quite helpful for me since I can hook my own read_handler for any partition on any disk, and use libfat to read files off it. Here is an example: typedef struct filedesc { diskinfo* disk_info; part_entry* partition; } filedesc; static filedesc rFd; static int fat_disk_read_handle(intptr_t fdp, void* buf, size_t nbyte, libfat_sector_t sector) { filedesc* fd = (filedesc*) fdp; int num_sectors = nbyte / LIBFAT_SECTOR_SIZE; int status; sector += fd->partition->start_lba; status...

Fix breakage in the "hide" option support patch: - The code which initialized the global variable "dapa" was lost in commit 81c203f2, therefore EBIOS access did not work properly. Fixed by removing the global variable completely and moving all bounce buffer handling into read_sector() and write_sector(). - write_sector() copied data to the bounce buffer, but then

...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...
