* lua: update for Syslinux 4Geert Stappers2010-07-012-6/+16
| | | | Update the lua code to work with Syslinux 4.

| * MCONFIG: add -Wno-error to .lnx filesH. Peter Anvin2010-07-011-1/+1
| | | | | | | | | | | | | | Again, .lnx files are test vehicles... erroring out due to warnings makes no sense. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
| * MCONFIG: .lnx files are for testing, don't do _FORTIFY_SOURCEH. Peter Anvin2010-07-011-1/+2
| | | | | | | | | | | | | | | | .lnx files are strictly a testing vehicle. It makes absolutely no sense to enforce the often rather arbitrary rules of _FORTIFY_SOURCE on those, so override the default _FORTIFY_SOURCE setting. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
| * ifplop.c32: Detect if PLoP USB/CD INT13h hook is enabled/disabledGert Hulselmans2010-07-012-1/+166
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New module which detects if the PLoP Boot Loader already has booted a CDROM or USB drive by checking for the presence of the PLoP INT13h hook. The following assembly code (NASM) can detect the PLoP INT13h hook: mov eax,'PoLP' ; Reverse of 'PLoP' mov ebp,'DKHC' ; Reverse of 'CHKD' int 13h cmp eax,' sey' ; Reverse of 'yes ' jz plop_INT13h_active Signed-off-by: Gert Hulselmans <gerth@zytor.com> Signed-off-by: H.

| | * chain.c32: pass partition number to stage2 of Grub LegacyGert Hulselmans2010-06-271-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Grub Legacy stage2 will read the install_partition variable from memory address 0x8208. We only need to change the value at 0x820a to the correct partition number: -1: whole drive (default) 0-3: primary partitions 4-*: logical partitions Signed-off-by: Gert Hulselmans <gerth@zytor.com>
| | * chain.c32: only pass partition number in DH, when grldr= is usedGert Hulselmans2010-06-271-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add grldr= as boot parameter, so the partition number is only passed to grub4dos grldr, when grldr= is used. Currently the partition number is passed in DH unconditionally. As consequence, grldr will set its root partition on which is searches its menu.lst to (hd0), because -1 (whole drive) is passed in DH as root partition: chain.c32 file=/grldr When the conditional check, this problem is solved: chain.c32 file=/grldr Grub4dos will search all partitions for its menu.lst When you want to set the root partition, use something like the following: chain.c32 hd0,2 grldr=/grldr chain.c32 fs grldr=/grldr Signed-off-by: Gert Hulselmans <gerth@zytor.com>

| | | | | | | | | | Add keeppxe to usage output. Cleanup some comments.
| * Export the 64-bit partition offset and use it in chain.cH. Peter Anvin2010-06-272-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | When used with the "fs" option to chain.c32, we need to know our own filesystem offset. That means knowing if we used the MBR vs GPT partition information, as well as if we ended up using the passed-in information or not. Resolve this by providing an explicit pointer to the current partition offset. Eventually this should be replaced by some kind of statfs() call. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

If the return value is NULL, display an error message. Unfortunately, it appears that COM32 getcwd is not working properly at this moment, it calling the COMBOOT call and getting an empty string.
