3497f157fd On serious boot errors, dont lock the machine. Instead, wait 3 seconds
and call the ROM BASIC vector. This might behave differently on different
machines, but normally it allows to reboot without power-cycling.

62031ff978 fix some disk handling problems introduced in the last commits:
-read retries were botched, use the right sector count
-read-ahead buffer was effectively unused
-concentrate the handling of the weird BIOS geometry report at one place
-fallback for old floppies left cylinder count uninitialized

b815df141c Only use the total number of sectors information field from the EDD if
the bit is set that declares the geometry valid. The spec itself says
that this field isn't covered by the "geometry valid" bit, but at
least one BIOS implements it that way.

8371eb7a88 Clean up the BIOS disk matching code a bit (better naming, one structure
and sysctl to export to userland). Also, only use total number of sectors
given in the extended parameters if the physical chs geometry is
marked invalid. Hopefully fixes a problem where BIOSs would not correctly
fill in this field.

0cb921e61e change the interface for getmementry() to hold the iterator in an

Now we can "error" and "end of list" cleanly; this should fix the
problem where the last list element was ignored.

cb2e02af94 Make this compile and work again after the assembler update.
The new assembler doesn't allow 16-bit relocations involving arithmetics
with 32-bit variables. (The old one did silently truncate, which was
the right thing in our case.) Further, the new assembler uses to scatter
size prefixes around if the size of the operation is not explicitely
specified, even if the result is nonsense, eg for moves to segment
registers or control registers.
Add some debugging code (generating printouts) and comments.
Remove the !BOOTROM code which was intended for a DOS harness but isn't
that useful anymore.
Some cleanup and formatting to make it more similar to the other
startup code variants.

0fcf083702 Add loadfile.c (stolen from Jason's alpha/stand/common/loadfile.c)
loadfile.h contains macros that are supposed to be MD, but loadfile.c is now MI.
Fixes:
- a.out support
- pass information values via an array not global variables
- don't assume that you can access memory directly.
- remove MD parts
- remove some printfs.
XXX:  loadfile.c needs to be moved somewhere where other ports can use it.
XXX2: read() routines on the i386 don't appear to set errno on failure.

cbb7aa93f0 from FreeBSD:
wpaul       1998/07/02 08:36:36 PDT

  Modified files:
    sys/i386/boot/biosboot start.S
  Log:
  Add workaround to allow the FreeBSD boot block to work on
  Kapok Computer Co. notebook with AMI 'WinBIOS' which seems to insist
  on having a short jump and nop as the first instructions in the
  boot sector code. The prevailing theory is that the BIOS is doing
  some sort of boot sector virus detection and refusing to run any
  boot block that doesn't start with the same instruction sequence as
  MS-DOG boot sector code. If this is the case, it would be nice if it
  actually printed an error message to this effect instead of just
  saying 'FAILED.'

  This workaround has no effect on the boot sector code other than to
  increase its size by three bytes.
