rillig | fix misspellings of 'available' and nearby typos
|

erh | Fix bootxx_* and boot on machines where the bios sets high bits of %eax on success.

| 16-Jun-2011 |
joerg | branches: 1.21.12; 1.21.26;
Add an optional MD calling convention flag for use in libsa when space
optimisation is critical. Use this on i386 to switch to register passing
calling convention for the file system entry points and most assembler
call backs that have to preserve at least 3 registers.

Utilize movz[bw]l to save a few instrutions and bytes of .text.
|
| 1.19 |
| 21-Nov-2009 |
dsl | branches: 1.19.4;
Preserve %ds over bios calls.
Not strickly necessary because real_to_prot doesn't normally rely on in.
However it caused much confusion while debugging, and does no harm.

junyoung | Massive renames for consistency:
biosdiskreset -> biosdisk_reset
biosread -> biosdisk_read
get_diskinfo -> biosdisk_getinfo
int13_extension -> biosdisk_int13ext
biosextread -> biosdisk_extread
int13_getextinfo -> biosdisk_getextinfo
struct biosdisk_ext13info -> biosdisk_extinfo
BIOSDISK_EXT13 -> BIOSDISK_INT13EXT
BIOSDISK_EXT13INFO_V{2,3} -> BIOSDISK_EXTINFO_V{2,3}
EXT13_* -> EXTINFO_*
|

junyoung | get_diskinfo():
Return status code in bits [31:24] of %eax. 0 for success, otherwise failure.
|
| 1.15 |
| 22-Jun-2005 |
junyoung | Do not mix assembly-style comments and C-style comments.
|
| 1.14 |
| 13-Jun-2005 |
junyoung | Remove trailing spaces.
|
| 1.13 |
| 16-Apr-2003 |
dsl | branches: 1.13.2;
C code now sets length of disk info structure
|
| 1.12 |
| 08-Mar-2003 |
dsl | Don't trust %bp to point to same place in real and protected modes.
prot_to_real preserves %ebp but changes %ss and %sp.
(ok if real %ss is offset n*64k from protected %ss - which it has been)
|
| 1.11 |
| 05-Feb-2003 |
dsl | Remove unused defines
|
| 1.10 |
| 01-Feb-2003 |
dsl | Change all .S files to use .code16 and .code32
Support 32bit addresses >64k as valid on bios calls.
Move stack for dosboot and biosboot to >64 so stack doesn't hit data.
Use disk sector number passed by mbr code to select default partition
(the mbr code doesn't do this yet).
NB only biosboot and dosboot have been tested so far.
(changes approved by christos and fvdl)

| 10-Oct-2002 |
dyoung | Introduce biosdiskreset(), and call it to reset the disk (with Int
0x13 Function 0) after a read error. This is a requirement mentioned
in most BIOS documentation.
This answers PR 18591.
Incidentally, on the Soekris Engineering net45x1 single-board
computer, this fixes a bug where the bootloader corrupts the kernel
while loading it from certain varieties of CompactFlash card
(especially varieties identified by NetBSD as <TOSHIBA THNCF064MBA>).

Actually return the BIOS error code (if any) generated by the reads
|
| 1.7 |

fvdl | branches: 1.7.8;
Shifting ecx without explicit prefix in real mode won't work.
|
| 1.6 |
| 30-Mar-1999 |
drochner | 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
|
| 1.5 |
| 08-Mar-1999 |
fvdl | * 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.

ws | Fix a thinko which still prevented this to run on non-int13-ext machines.
Thanks to entropy@zippy.bernstein.com for pointing this out and testing the fix.
|
| 1.3 |
| 27-Oct-1998 |
ws | Fix typo which prevented this from working
on disks without int13-extension support.
|
| 1.2 |
| 15-Oct-1998 |
ws | Add int13 extension support

Initial revision
|
| 1.1.1.1 |
| 14-Mar-1997 |
perry | Initial import of new boot code, created by Matthias Drochner with a
little hacking by me. This isn't strictly identical to his 920312
release -- I've hacked it a bit -- but since we are taking over change
control it doesn't matter much.

| 1.7.8.1 |
| 20-Nov-2000 |
bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
