| | | | | | | Dump all the VESA modes; give functional timestamps for the cpio members. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* sysdump: first working version (can dump lowmem over TFTP)H. Peter Anvin2010-02-068-5/+387
| | | | | | | | Most of the infrastructure for sysdump, and enough to make it useful. Sysdump will produce a gzipped cpio archive containing individual data members; for now only a memory dump of lowmem. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | <syslinux/pxe.h> was using segoff16_t, <com32.h> was using far_ptr_t for the same thing -- use the same type so the macros are available for both. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* chain.c32: Handle nonlinear logical partitionssyslinux-3.85-pre3H. Peter Anvin2010-01-271-5/+8
| | | | | | | | | | | Some partitioning program, including at least parted, apparently create the list of logical partition headers nonlinearly with the partition themselves. Thus, make it a requirement that then fit inside the overall extended partition, but not inside the corresponding sublogical partition. Reported-by: Gert Huselmans <gerth@zytor.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Add support for "vga=current"H. Peter Anvin2010-01-221-0/+3
| | | | | | "vga=current" is a user-friendly synonym for "vga=0x0f04". Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* dmi_processor.c: remove unreachable table valuesH. Peter Anvin2010-01-101-50/+2
| | | | | | A uint8_t can't have values all the way up to 0x12e... Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* disk/bootloaders.c: fix bogus const in get_bootloader_string()H. Peter Anvin2010-01-102-2/+2
| | | | | | | get_bootloader_string() takes a mutable first argument; the call chain does have call paths on which this argument will be modified. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* disk/ata.c: fix signedness weirdness in ata_id_c_string()H. Peter Anvin2010-01-101-1/+1
| | | | | | Fix signedness weirdness in ata_id_c_string(), thus killing a warning. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* com32/lib: remove unused variable in syslinux_getadv()H. Peter Anvin2010-01-101-1/+1
| | | | | | Remove unused variable, thus removing a warning. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* zlib: fix warning in crc32.cH. Peter Anvin2010-01-101-1/+1
| | | | | | Fix a signed/unsigned warning in crc32.c. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* com32/lib: fix external prototype for __vesacon_open()H. Peter Anvin2010-01-101-1/+1
| | | | | | | The external prototype for __vesacon_open() was incorrect; this is a good example of why external prototypes are bad, incidentally. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* com32/lib: fix inappropriate & in sys/colortable.cH. Peter Anvin2010-01-101-1/+1
| | | | | | The & is incorrect... not actively harmful, but generates a warning. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* com32/lib: add cast in __parse_argv()H. Peter Anvin2010-01-101-1/+1
| | | | | | | | | ALIGN_UP_FOR() returns the type of the original pointer, but we want it to be the type that we're actually going to use. Perhaps ALIGN_UP_FOR() should be changed, but for now, just add the proper cast. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* libgcc: fix signedness warning in __moddi3()H. Peter Anvin2010-01-101-1/+1
| | | | | | Intentional cross-signedness pointer passing, add a cast. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* com32/lib: fix unused argument warning in fdopendir()H. Peter Anvin2010-01-101-0/+2
| | | | | | fdopendir() is a stub, and probably will remain such. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* com32/lib: fix unused parameter warning in chdir()H. Peter Anvin2010-01-101-0/+4
| | | | | | chdir() is a stub at the moment... to be fixed in Syslinux 4. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* Makefile: replace -W -Wall with centralized $(GCCWARN)H. Peter Anvin2010-01-103-6/+6
| | | | | | | | | Replace -W -Wall hardcoded into a bunch of Makefiles with $(GCCWARN), a centralized variable defined in the root MCONFIG. Add -Wstrict-prototypes to the list of global warnings: we should never have non-prototyped declarations. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* cmenu: clean up some () that should be (void)H. Peter Anvin2010-01-103-4/+4
| | | | | | | () is not a prototype, and means (...) not (void) in C. Replace with (void). Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* chain.c32: simplify the grub4dos supportH. Peter Anvin2010-01-101-13/+9
| | | | | | | Grub4dos (like Grub in general) uses the same partition numbers as Linux (and chain.c32), minus one. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* chain.c32: add grldr= command for Grub4dosKim Mik2010-01-101-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | grldr of Grub4dos wants the partition number in DH: 0xff: whole drive 0-3: primary partitions 4-*: logical partitions Hmmm... there really isn't a huge reason not to do this unconditionally, at least unless it's known to cause problems. It would be better, of course, if grldr used the standard DS:SI, but it doesn't, so oh well. Some info of a Grub4dos developer (Tinybit): GRLDR can be loaded at any address with alignment 16(i.e., a possible segment base address). Generally you want to load it at 0000:7C00, or at 2000:0000. Of course you never load it at 0000:0000 or similar. Before jumping to the entry point at the very beginning of GRLDR, you should setup DL=(BIOS drive) and DH=(partition number). For partition numbers, 0 - 3 are primary, 4 - 0xFE are logical. (DH=0xFF) stands for whole drive(unpartitioned). DH will later be passed to install_partition(the third byte, from bit 16 to bit 23). http://www.boot-land.net/forums/index.php?showtopic=8457&st=20&start=20 post #22
* Change () prototypes to (void)H. Peter Anvin2010-01-0612-38/+48
| | | | | | | | () means the same as (...) in C, not the same as (void) as it does in C++. It is generally misused to mean (void), though. Actually write what we mean... this is C, after all. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* | chain.c32: add support for booting the Recovery Console of Windows NT/2K/XPKim Mik2009-12-281-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch for chain.c32 adds support to boot the Recovery Console of Windows NT/2K/XP. Normally when you want to boot the recovery console, you need to patch "cmdcons\0" into the bootsectorof the partition (8 bytes starting at 0x3 (4th byte)). We can do this patching in memory: strcpy((char *) 0x7c03, "cmdcons"); To boot the recovery console with chain.c32: chain.c32 cmldr=/cmldr - Gert Hulselmans
