10d23bba69 Needs a.out support built into the loader. 2002-03-28 19:09:44 +00:00

fb74e5f595 Add splitfs vfs layer into libstand, which allows loading big kernels and
modules split across several physical medias. Following is how it works:

The splitfs code, when asked to open "foo" looks for a file "foo.split"
which is a text file containing a list of filenames and media names, e.g.

	foo.aa "Kernel floppy 1"
	foo.ab "Kernel floppy 2"
	foo.ac "Kernel and modules floppy"

For each file segment, the process is:

- try to open the file
- prompt "Insert the disk labelled <whatever> and press any key..."
- try to open the file
- return error if file could not be located

RE team is free to use this feature in the upcoming 5.0-DP1.

0889b9be41 - Add 'fwrite' and 'fseek' words for writing to and seeking on files.
- Change the 'fopen' keyword to accept a mode parameter.  Note that this
  will break existing 4th scripts that use fopen.  Thus, the loader
  version has been bumped and loader.4th has been changed to check for a
  sufficient version on i386 and alpha.  Be sure that you either do a full
  world build or install or full build and install of sys/boot after this
  since loader.old won't work with the new 4th files and vice versa.

0f2c85b335 Add support for loading bzip2-compressed kernels and modules. This support
is turned off by default and could be enabled by defining LOADER_BZIP2_SUPPORT
make variable. Also make gzip support optional (turned on by default) -
it could be turned off via LOADER_NO_GZIP_SUPPORT make variable.

Please note, that due to limit on the amount of memory available to the
loader(8), it is possible to load modules/kernels compressed with the smallest
block size supported by the bzip2 - 100k (`-1' bzip2(1) option), however
even in this mode bzip2(1) usually provides better compression ratio than
gzip(1) in its best compression mode.

ad41f9a8f7 Teach the loader how to find the system ACPI information, and autoload
the ACPI module if the system apperars to be ACPI compliant.

This is an initial cut; the load should really be done by Forth support
code, and we should check both the BIOS build date and a blacklist.

48a0c4ea04 Mega i386 loader commit.
- Don't hard code 0x10000 as the entry point for the loader.  Instead add
  src/sys/boot/i386/Makefile.inc which defines a make variable with the
  entry point for the loader.  Move the loader's entry point up to
  0x20000, which makes PXE happy.
- Don't try to use cpp to parse btxldr for the optional BTXLDR_VERBOSE,
  instead use m4 to achieve this.  Also, add a BTXLDR_VERBOSE knob in the
  btxldr Makefile to turn this option on.
- Redo parts of cdldr's Makefile so that it now builds and installs cdboot
  instead of having i386/loader/Makefile do that.  Also, add in some more
  variables to make the pxeldr Makefile almost identical and thus to ease
  maintainability.
- Teach cdldr about the a.out format.  Cdldr now parsers the a.out header
  of the loader binary and relocates it based on that.  The entry point of
  the loader no longer has to be hardcoded into cdldr.  Also, the boot
  info table from mkisofs is no longer required to get a useful cdboot.
- Update the lsdev function for BIOS disks to parse other file systems
  (such as DOS FAT) that we currently support.  This is still buggy as
  it assumes that a floppy with a DOS boot sector actually has a MBR and
  parses it as such.  I'll be fixing this in the future.
- The biggie:  Add in support for booting off of PXE-enabled network
  adapters.  Currently, we use the TFTP API provided by the PXE BIOS.
  Eventually we will switch to using the low-level NIC driver thus
  allowing both TFTP and NFS to be used, but for now it's just TFTP.

c8bb85f758 Add the new cdldr CD bootstrap loader. This patch includes the following:
- Fix btxldr to preserve a NULL bootinfo pointer when it copies the kernel
  arguments.
- Add the cdldr bootstrap program.  This program is tacked onto the
  beginning of the standard 3rd stage boot loader (/boot/loader) to form
  the CD boot loader (/boot/cdboot).  When a CD is booted, the cdboot file
  is copied into memory instead and executed.  The cdldr stub emulates the
  environment normally provided by boot2 and then starts the loader.  This
  booting method does not emulate a floppy drive, but boots directly off of
  the CD.  This should fix the problems some BIOS's have with emulating a
  2.88 MB floppy image.
- Add support to the loader to recognize that it has been booted by cdldr
  instead of boot2 and use a simpler method of extracting the BIOS boot
  device.

627249c7b1 Substantially revamp the way that we determine the amount of memory available
for our use.  Use the same search order for BIOS memory size functions
as the kernel will later use.

Allow the loader to use all of the detected physical memory (this will
greatly help people trying to load enormous memory disk images).

More correctly handle running out of memory when loading an object.

Use the end of base memory for the top of the heap, rather than
blindly hoping that there is 384k left.

Add copyrights to a couple of files I forgot.
