drochner 5d86b86370 #ifdef out the last change for the branch 1999-04-01 19:36:09 +00:00
drochner 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.

drochner 99a84ef740 sync to changed biosdisk interface again 1999-04-01 16:09:49 +00:00
fvdl fb1b0e7a0b Shifting ecx without explicit prefix in real mode won't work. 1999-03-30 22:35:21 +00:00
drochner 17de7b2576 adapt to set_geometry change: we don't have to correct the geometry 
anymore
 1999-03-30 17:58:05 +00:00
drochner 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

drochner 4feae58ec1 sync to changed geometry handling in the standalone code 1999-03-30 11:51:35 +00:00
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.

sommerfe 82f8a7dee9 Turn off biosboot_ser until makefile issues get worked out.. 1999-03-14 05:50:38 +00:00
fvdl 35d517b9f1 Hack to make biosboot_ser work. 
XXX The makefile structure in src/sys/arch/i386/stand is very bad.

tron 32e0182e15 $(OBJS) -> ${OBJS} 1999-03-13 20:58:25 +00:00
sommerfe fc47c0c742 Also build serial bootblocks by default, installing into 
/usr/mdec/biosboot_ser.sym
Change Makefile.booters to not assume `version' file is in source directory.

sommerfe df8e0043e3 Fix compile warning in getcomaddr() 1999-03-12 04:14:37 +00:00
fvdl 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.

fvdl bc38bb1052 Declare nhd to be unsigned char, as we're only copying one byte to it. 
From Matthias Drochner.
 1999-03-11 12:34:36 +00:00
drochner b477d700f2 add support for 3c905b TX 1999-03-10 10:37:38 +00:00
fvdl bdb770bc34 Create a list of native disks too, and make it retrievable. It contains 
all matching BIOS disks per entry, so that we have complete match info.
Enable the matching code.
 1999-03-10 01:28:24 +00:00
drochner 743494ae88 add a function to pass the "memory map" ie the outcome of INT15/0xe820, 
to the kernel
 1999-03-08 21:44:48 +00:00
drochner 0cb921e61e change the interface for getmementry() to hold the iterator in an 
argument and to return success or error explicitely.
Now we can "error" and "end of list" cleanly; this should fix the
problem where the last list element was ignored.
 1999-03-08 21:38:28 +00:00
fvdl f8e221511b * query BIOS geometry information, possibly using the int 13 extensions. 
* pass them on to the kernel
* print a message if the 2nd stage bootloader returns (i.e. fails)
  instead of just hanging.

he e9f9c1625e Add handling of OMAGIC files, where exec header isn't part of the 
text segment.  Needed for woring installboot, since biosboot.sym is OMAGIC.
 1999-03-07 20:03:44 +00:00
fvdl 5a32d4bb8b Make bootblocks really work this time. From Christos. 1999-03-05 20:33:08 +00:00
christos 4b494ca224 Fix the symbol reading problem... 1999-03-04 20:46:23 +00:00
simonb 1397fd691b fix spel. 1999-03-01 12:46:16 +00:00
drochner d57c7b76ca replace ENTRY() label in data segment which broke the code completely 1999-02-28 11:45:44 +00:00
drochner 9e8c9e9594 -pull in exec.c, needed since loadfile.c 
-don't pull in tftp.c anymore, it's in libsa now
 1999-02-24 19:38:17 +00:00
drochner f1d1de8c7a moved to mi lib/libsa 1999-02-24 19:32:34 +00:00
drochner eac4e51111 redirect the linker's stderr to the protocol file too 1999-02-19 19:53:01 +00:00
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.

drochner fd3ad59373 make the ethernet address an unsigned char array to avoid sign extension 
when it is printed
 1999-02-19 19:30:46 +00:00
drochner 0ce9e35aae add boot ROM support for the DMA-only 3com network adapters, tested with 
3c900b-Combo only for now
 1999-02-19 19:22:52 +00:00
dean 6dc3d1eae8 Put back bsd.own.mk and added comment explaining why it must be included. 1999-02-14 02:56:19 +00:00
lukem dcab0210a0 convert from NOxxx= to MKxxx=no. 
include <bsd.own.mk> if testing a MKxxx variable.
 1999-02-13 02:54:17 +00:00
dean c372a9b915 Remove bsd.own.mk include 1999-02-12 23:48:46 +00:00
cjs 8a3ac60bb8 Change NOMAN to MKMAN. 1999-02-12 05:15:35 +00:00
cjs 3e90f302b6 Don't give exit() a parameter, as libstand version doesn't take one. 1999-02-12 05:14:22 +00:00
tron 2fefe24803 Remove "lib" directory only during "make cleandir" so that ".depend" 
doesn't get nuked during "make clean".
 1999-02-07 18:25:54 +00:00
tron 08c7376961 Remove "lib" directory created during build process while doing 
"make clean" or "make cleandir".

christos 736a561afb Add my name in the copyright, since the code looks very different now. 1999-01-30 17:51:52 +00:00
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.
 1999-01-30 17:46:53 +00:00
christos 07b1febfb8 - Use MARK_ENTRY instead of MARK_START. 
- ELF changes. Now an ELF installboot installs ELF bootblocks properly.
 1999-01-30 17:45:42 +00:00
christos 371363a158 Add exec.c here and bump version for elf. 
XXX: This code has not been tested!
 1999-01-30 17:44:10 +00:00
christos 25fc1fa758 Add exec.c here... 1999-01-30 17:43:38 +00:00
christos ad9c7a287c Remove exec.o, and make necessary changes for elf. 1999-01-30 17:43:10 +00:00
thorpej 191dab44fa Um, last rev was kind of backwards... actually build exec.o so that 
the boot block links.
 1999-01-29 22:13:42 +00:00
christos e58bb79483 Merge XMS changes from exec_fromdos.c 1999-01-29 18:49:08 +00:00
christos e25e5c88f9 Both booters need exec.o now. 1999-01-29 18:47:58 +00:00
christos 35ca0db06c Revert, wrong place for this. 1999-01-29 18:47:24 +00:00
christos 6cadeb1ea6 Add exec.c here. 1999-01-29 18:46:15 +00:00
christos 3c7776f1b6 exec.c has all the info now. 1999-01-29 18:45:34 +00:00
