AIR-BOOT.ASM@ 30

Last change on this file since 30 was 30, checked in by Ben Rietbroek, 14 years ago

AiR-BOOT v1.07 -- As released with eCS v2.1. [2011-05-06]
Signature-date: 2006-03-13. (incorrect)
Trunk contains buildable v1.07 version as distributed with eCS v2.1.
Directory 'tags' contains v1.06 & v1.07 reference versions
built for all languages. Note that language ID for 'Dutch' changed
from 'DT' to 'NL' in v1.07 and that the v1.06 reference version also
uses 'NL' for 'Dutch'.
Also note that helper programs like the installer and setaboot are
are only modified for the OS/2 versions in v1.07.
The signature-date for v1.07 incorrectly states the same
date as for v1.06. The signature-version is correct.
Removed other binaries. (cd-rom images, old releases, etc.)
The tags serve as reference versions:

v1.06: rebuilt from source. (tags/v1.06r)
v1.07: built as released with eCS v2.1. (tags/v1.07r)

	20	; Rousseau: # Fixes #
	21	; -------------------
	22	; # Huge Drives and LVM #
	23	; When using disks >512GB under eComStation, the drive geometry changes to
	24	; 127 or 255 sectors per track. Since LVM-info is written at the last sector
	25	; of a track, and AiR-BOOT uses the geometry of the MBR, it cannot find the
	26	; LVM-info and the eCS partition / volume bootsector.
	27	; This has been fixed.
	28	; Now, when an eCS-partition is discovered and the drive is >512GB, AiR-BOOT
	29	; will use the eCS geometry to locate the LVM-info and the bootsector.
	30	;
	31	; # Special loader handling #
	32	; The special handling of partition boot-loaders has been enhanced to
	33	; enable booting of legacy sysems on huge drives with or without OS/2
	34	; extended geometry.
	35	;
	36	; # eComStation boot-through after phase 1 #
	37	; A special functionality is implemented to directly boot the newly
	38	; installed system ; when installing eCS without showing the Boot Menu,
	39	; independant of user settings.
	40	; This works in conjuntion with the OS/2 specific SETABOOT.EXE program,
	41	; also part of this AiR-BOOT package.
	42	;
	43	; # Math, Debug, Conv and Aux modules #
	44	; These are used for 32-bit arithmatic on 16-bit code,
	45	; debug the booting process, converting between data-types
	46	; and outputting log-data to the com-port.

	59	; We actually don't want to use this directive because it generates extra
	60	; NOP instructions that we can do without.
	61	; Relative conditional jumps that are out-of-range are manually reworked by
	62	; skipping an unconditional jump to the target on base of complementary
	63	; condition logic and temporary labels.
	64	; TASM also has a bug in that when the .ERR2 directive is used when the .386 directive
	65	; is in effect, the JUMPS directive is also active and cannot be turned off.
	66	; NOJUMPS seems to have no effect in this situation.
	67	; In this case 4 NOP instructions are generated after forward referencing jump
	68	; instructions, to allow for automatic recoding by TASM.
