| | | | | | | | | | | | | | 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 Hulselmans2010-07-013-1/+168
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | The LBA for getonesec and getlinsec is in EDX:EAX, but both DL and AX are function inputs to INT 13h (drive number and function number). We need to preserve the LBA across *both* those, otherwise retries will not function. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

Make sure that we set Hidden to zero -- we don't use Hidden (yet, although the ebios and cdrom code should be merged!) but we pass it to the PM code, which will produce *really* wrong results...

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

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>

| * | Export the 64-bit partition offset and use it in chain.cH. Peter Anvin2010-06-275-14/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | diskstart: if no partition info is available, use bsHiddensyslinux-4.00-pre63H. Peter Anvin2010-06-261-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we have no partition information available, use the bsHidden field (which is set by the extlinux installer in the case of non-FAT). This gives at least a hope of working correctly (for < 2 TiB disks, at least) with the stock Vista/Win7 MBR. Also, add a check for partition type != 0. This helps catch the case when DS:SI points into all-zero memory. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
