* 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>

* Export the 64-bit partition offset and use it in chain.cH. Peter Anvin2010-06-271-2/+3
| | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | The ifcpu.c32 and ifcpu64.c32 modules take arguments including the form <true_label> -- <false_label>. It is convenient to allow these labels to be not just a single word, but to include parameters. This is useful for <TAB>-editing and modifying the command-line to include parameters you'd like to pass. Not-yet-tested: Shao Miller <shao.miller@yrdsb.edu.on.ca>
* | chain.c32: add support for loading GRUB stage2Paul Bolle2010-06-071-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds (basic) support for GRUB stage2 image files. Loading a stage2 image will probably give you a GRUB prompt, with GRUB's "root" set at "(hd0)" (ie, entire first disk). Maybe the "root" will differ in less common setups. (One can of course select another disk and/or partition with GRUB's "root" command.) This has only been tested with version 3.2 stage2 images (as used by GRUB 0.97). I'm not familiair with differences with other versions. GRUB's loading mechanism allows to somehow provide stage2 with the selected disk and partition, BSD slice, etc. (ie, to tell stage2 what it's "root" is). I don't yet understand the notation used in that mechanism. Besides, since stage2 images will not necessarily be loaded from the disk (and partition, etc.) they were installed to, it seems best to just use the first disk. GRUB stage1_5 image files load quite similarly. However, for some reason, a short test only got those images to print an error ("Error 17"). This could be related to the partition info these images are provided with when they're loaded. I have never used stage1_5 images, and do not know how to properly use and configure those, so my test stopped there, and stage1_5 images are not supported.
