Luchezar Georgiev 6e7cf96323 By Eduardo Casino-Almao: 
adds DBCS support to DOS-65-23 (Determine if a character represents
yes/no response) as specified by RBIL, and fixes DOS-63-00 (Get
Double Byte Character Set lead-byte table.) It now returns the DBCS
table from the active NLS package, not the harcoded one.

from Tom: improve behaviour on failed FindFirst call and return to app not DOS

 2004-05-29 09:51:47 +00:00
Bart Oldeman dace548223 (mostly from Lucho) deal with the correct structure for generic and 
query ioctls. Fixes issues with 3rd party device drivers (or ones that use
dsk.c)

 2004-05-10 00:24:33 +00:00
Bart Oldeman 6947542a5e Initialise all int vectors except the ones at 70:xxxx using a table. 
Convert setvec into a function that disables/enables ints (init code only
for now, resident code will follow later); cli/sti (disable/enable) are
now macros (inlined).


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@918 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-05-04 09:32:16 +00:00
Bart Oldeman ecfcb9be29 dir_read() no longer updates the diroff counter. This eliminates the NEW 
field, simplifies remove_lfn_entries(), and avoids a bug if you delete
the first entry in the root directory on FAT32.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@911 6ac86273-5f31-0410-b378-82cca8765d1b

Bart Oldeman 2734dd94ae Fix Borland prototype warnings. Use kernel 2034 rc version tag for 
wider testing.

Bart Oldeman 6f6ceadebc As per a suggestion from Arkady: use CPU to enforce 8086 etc instructions. 
git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@879 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-04-13 20:41:15 +00:00
Bart Oldeman 7eb9514377 Move the ddt bitfields to df_descflags. Let SetLogDev call GetLogdev, 
eliminating common code.

 2004-04-13 10:54:33 +00:00
Bart Oldeman 5d712fc2a6 Avoid bitfields for fnodes, using flags instead. 
Replaced droot field by checks for f_dirstart == 0.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@867 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-04-13 10:46:37 +00:00
Bart Oldeman e6e3b7a3a4 Use the "small" model for the init code (split code/data). This will enable 
us to use the same CS for resident and init code for Watcom (Borland's
too big), and share a bit.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@859 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-04-10 10:59:57 +00:00
Bart Oldeman a7ca14c46c Use pascal calling conventions for execrh(). 
git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@848 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-04-09 11:16:03 +00:00
Bart Oldeman 7ae98cee2a Introduce VA_CDECL: only Turbo C 2.01 needs an explicit cdecl for printf, 
all other compilers can use it with pascal or "register" calling conventions.
Saves ~50 bytes for the init code.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@845 6ac86273-5f31-0410-b378-82cca8765d1b

Bart Oldeman d5cb4e950c Fixed screwed up comment sequence. 
git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@831 6ac86273-5f31-0410-b378-82cca8765d1b

Bart Oldeman 9aa77bef50 Get rid of SFT_M* mode values. O_* values are sufficient. 
git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@830 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-03-27 00:23:06 +00:00
Bart Oldeman 0f4d6ea6a1 Define O_ACCMODE and use it instead of "3" for the open access mask. 
git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@828 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-03-26 23:20:55 +00:00
Bart Oldeman d17f333243 From Lucho (and I think Arkady had this as well at some point): 
save 33 bytes by eliminating a switch for memory/UMB access modes.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@822 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-03-25 00:20:20 +00:00
Bart Oldeman f63eea565a Made the main fnodes far so they can be in UMBs. 
Internally the kernel uses two near fnodes though, to save on codesize
and fmemcpy's if necessary. Having memory management on two fnodes is
a little silly but I just want to make sure with the panic message
that we never accidentally try to use three near fnodes at the same time.
(two are used at the same time by rename, commit, and merge_file_changes).
This can be cleaned up later.

Anyway. 644736 bytes free conv memory isn't bad.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@821 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-03-23 22:45:38 +00:00
Bart Oldeman ce290a033f Eliminate f_back field. 
extend() now uses f_cluster instead of f_back, while map_cluster makes
sure it's not set to LONG_LAST_CLUSTER (but to the cluster before it)
when calling extend().
extend() and first_fat() now return the new cluster number or
LONG_LAST_CLUSTER, just like find_fat_free()
Hopefully I didn't break anything... Initial testing was successful.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@816 6ac86273-5f31-0410-b378-82cca8765d1b

 2004-03-22 16:56:34 +00:00
Bart Oldeman 11a7b69e5c Make f_diroff an entry offset so it can be 16bits. Enforce the 65536 
entry limit in dir_read(). Saves 80 bytes or so + 2 bytes in every f_node.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@811 6ac86273-5f31-0410-b378-82cca8765d1b
 2004-03-22 10:29:26 +00:00
Bart Oldeman 0d6d0b8523 (with Lucho) -- remove the dosnames path 67 length check. Review the places 
where it really matters (chdir and mkdir).


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@796 6ac86273-5f31-0410-b378-82cca8765d1b

Bart Oldeman d61defe941 From Lucho: move NLS #defines to nls.h. Move config structure to config.h. 
Some cosmetic changes.

 2004-02-23 23:26:01 +00:00
Bart Oldeman de444743cc Define I386 and I186 more cleanly. 
Add (UWORD) casts to silence the compiler.
Optimize (head*sector) to secs_per_cyl
Add BORLANDC to compiler list and simplify startup printf to one message.
#pragma enable_message(130) for Watcom C causes it to behave a little more
like Borland in terms of warnings.
