mycroft 6816b631ab Nit: Make bootrealseg conforming. 1999-11-07 01:06:37 +00:00
drochner db5d01fc72 back out the "ep"/"ex" guessing part of the previous - the check was
removed from the kernel and the device name is only informational now

mycroft 3c702c1d8d Recognize the 3c595, and use `ex' for 3c90x now. 1999-11-03 12:38:54 +00:00
mycroft dfc00b5b24 Back out the GDT changes in the previous. Didn't mean to commit that. 1999-11-03 09:55:32 +00:00
mycroft 1ee8f66dfe Picking a few nits...
* The direction flag wasn't set right in the presence of ROMDEBUG.
* There were missing data32's.
* We weren't as careful as we should be with relocations.

kleink 5663256d0a Unlike in an i386 a.out assembler, where in an .align n directive n is meant
to be the logarithm to base 2 of the alignment, in an ELF environment n is
the actual alignment boundary; thus, adjust the directives accordingly.

Albeit the wonderful i386 architecture doesn't mind the smaller alignment in
an obvious way, it is likely to have resulted in some performance penalty
during the a.out->ELF transition.

fvdl 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.

fill in this field.

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

drochner 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.

christos 5699d1ab3d Remove exec.c from here. I want to make it obvious that it has to be built
with different flags from dosboot and biosboot. Although right now this
does not make a difference because we are building the libraries twice,
it can make a difference when we share the builds.

christos 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.

drochner 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.
