| | | | | | | | | | | dim@ compared clang IAS-built and GNU as-built boot0 and found them equivalent. IAS encoded one instruction using two bytes where GNU as used three, and another instruction using three bytes where GNU as used two. The net result is equivalent and tested, so there is no need to force IAS off for boot0. Notes: svn path=/head/; revision=320288

| | | | | | | | | | | | | | | | | not page aligned. To do this, use the ld script gnu ld installs on my system. This is imperfect: LDFLAGS_BIN and LD_FLAGS_BIN describe different things. The loader script could be better named and take into account other architectures. And having two different mechanisms to do basically the same thing needs study. However, it's blocking forward progress on lld, so I'll work in parallel to sort these out.

* A number of small changes to make the 'save choice to disk' safer,Luigi Rizzo2008-12-302-28/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and re-enable it as default. In particular: + re-enable the 'update' flag in the Makefile (of course!); + commit Warner's patch "orb $NOUPDATE,_FLAGS(%bp)" to avoid writing to disk in case of a timeout/default choice; + fix an off-by-one count in the partition scan code that would print the wrong name for unknown partitions; + unconditionally change the boot prompt to 'Boot:' instead of 'Default:' to make room for the extra code/checks/messages. Some of the changes listed below are also made to save space; + rearrange and fix comments for known partition types. Right now we explicitly recognise *BSD, Linux, FAT16 (type 6, used on many USB keys), NTFS (type 7), FAT32 (type 11). Depending on other options we also recognise Extended (type 5), FAT12 (type 1) and FAT16 < 32MB (type 4). + Add an entry "F6 PXE" when the code is built with -DPXE (which is a default now). Technically, F6 boots through INT18, so the prompt 'PXE' is a bit misleading. Unfortunately the name INT18 is too long and does not fit in - we could use ROM perhaps. The reason I picked 'PXE' is that on many (I believe) new systems INT18 calls PXE. Apart from the choice of the name for PXE/ROM/INT18, this should close pending issues on the 1-sector boot0 code and we should be able to move the code to RELENG_7 when it reopens. No boot0cfg changes are necessary. MFC after: 3 weeks Notes: svn path=/head/; revision=186598

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | boot0.S changes: + import a patch from Christoph Mallon to rearrange the various print functions and save another couple of bytes; + implement the suggestion in PR 70531 to enable booting from any valid partition because even the extended partitions that were previously in our kill list may contain a valid boot loader. This simplifies the code and saves some bytes; + followwing up PR 127764, implement conditional code to preserve the 'Volume ID' which might be used by other OS (NT, XP, Vista) and is located at offset 0x1b8. This requires a relocation of the parameter block within the boot sector -- there is no other possible workaround. To address this, boot0cfg has been updated to handle both versions of the boot code; + slightly rearrange the strings printed in the menus to make the code buildable with all options. Given the tight memory budget, this means that with certain options we need to shrink or remove certain labels. and especially: make -DVOLUME_LABEL -DPXE the default options. This means that the newly built boot0 block will preserve the Volume ID, and has the (hidden) option F6 to boot from INT18/PXE. I think the extra functionality is well worth the change. The most visible difference here is that the 'Default: ' string now becomes 'Boot: ' (it can be reverted to the old value but then we need to nuke 1/2 partition name or entries to make up for the extra room). boot0cfg changes: + modify the code to recognise the new boot0 structure (with the relocated options block to make room for the Volume id). + add two options, '-i xxxx-xxxx' to set the volume ID, -e c to modify the character printed in case of bad input PR: 127764 70531 Submitted by: Christoph Mallon (portions) MFC after: 4 weeks Notes: svn path=/head/; revision=185579

The code is completely compatible with the previous one, and with the boot0cfg program. Even the actual code is largely unmodified, with only minor rearrangements or fixes to make room for the new features. The behaviour of the standard build differs from the previous version in the following, minor things: + 'noupdate' is the default, which means the code does not write back the selection to disk. You can enable the feature at runtime with boot0cfg, or changing the flags in the Makefile. + a drive number of 0x00 (floppy, or USB in floppy emulation) is now accepted as valid. Previously, it was overridden with 0x80, meaning that the partition table coming from the media was used to access sectors on a possibly different media. You can revert to the previous mode building with -DCHECK_DRIVE, and you can always use the 'setdrv' option in boot0cfg + certain FAT or NTFS partitions are listed as WIN instead of DOS. + the 'bel' character on a bad selection is replaced by a '#' to make it clear that the system is not hang even if the machine does not have a speaker. This can be reverted back at compile time, or at runtime with an upcoming boot0cfg option. Additional features are available as compile time options, and may be become the default if deemed useful. In particular: + INT18/PXE boot (make -DPXE) This option enables booting through INT 18h (which on certain BIOSes can be hooked to PXE) by pressing F6. There is unfortunately no room to print the additional menu option. Also, to make room for the code, the 'Default: ' string is changed to 'Boot: ' + print current drive number (make -DTEST) Prints a line indicating the current drive number. This is useful to figure out what is going on for machines/bioses which remap drives in sometimes surprising ways. + disable numeric keys in console mode (make -DONLY_F_KEYS) Not really a significant option, but it is needed to make room for the -DTEST mode. + disable floppy support (make -DCHECK_DRIVE) Revert to the old behaviour of only accepting 0x80 and above as valid drive numbers.

* Fix a typo in previous commit: must call "putn" to print a crlf,Luigi Rizzo2008-11-261-1/+1

It was not noticed during tests because at that point %si points to a partition entry whose first byte is 0x80, which is both a terminator for the string and a non printable character.

* Pass the pointer to the selected partition in %si to the next stageLuigi Rizzo2008-11-261-2/+3
| | | | | | | | | | | | | | | | | | boot code. The bug was introduced in rev.1.13, and went unnoticed because FreeBSD's boot1 does not use it, but other systems might. (I have been struggling for almost a full day trying to figure out why a syslinux'ed partition would not boot when started with the FreeBSD /boot/boot0, only to realize that the bug was ours!) The space for the two extra bytes (push %si and pop %si) is reclaimed by removing an extra CRLF that is printed before booting. The bug is not a major one but if there is time it might be a good thing to merge it into the upcoming releases. Notes: svn path=/head/; revision=185339
