[Freedos-kernel] patch: floppy.asm
Hi! - prototypes fixed and syncronized with dsk.c. - more and better comments. - bugfix: when fl_lba_ReadWrite() converted to ASMPASCAL (and `ret' replaced by `ret 8'), "ret_AH" was remained as label for this tail (whereas other functions use plain `ret'); now ret_AH moved into another function. --- Begin Message --- diff -ruNp old/drivers/floppy.asm new/drivers/floppy.asm --- old/drivers/floppy.asm 2004-04-09 06:11:44.0 + +++ new/drivers/floppy.asm 2004-06-07 20:31:24.0 + @@ -28,15 +28,14 @@ ; $Id: floppy.asm,v 1.18 2004/04/09 13:11:22 bartoldeman Exp $ ; - %include "../kernel/segs.inc" - segment HMA_TEXT -; -; -; Reset both the diskette and hard disk system +%include "../kernel/segs.inc" +segment HMA_TEXT + ; -; BOOL fl_reset(WORD drive) +; int ASMPASCAL fl_reset(WORD drive); ; -; returns TRUE if successful +; Reset both the diskette and hard disk system. +; returns TRUE if successful. ; global FL_RESET @@ -44,199 +43,174 @@ FL_RESET: pop ax ; return address pop dx ; drive pushax ; restore address -mov ah,0; BIOS reset diskette & fixed disk + mov ah,0; reset disk int 13h + sbb ax,ax ; CF=1: error + inc ax ; return TRUE (1) on success, + ret ; FALSE (0) on error -sbbax,ax ; cy==1 is error - inc ax ; TRUE on success, FALSE on failure -ret - - -; ; -; Read disk change line status +; int ASMPASCAL fl_diskchanged(WORD drive); ; -; COUNT fl_diskchanged(WORD drive) -; -; returns 1 if disk has changed, 0 if not, 0x if error +; Read disk change line status. +; returns 1 if disk has changed, 0 if not, 0xFF if error. ; global FL_DISKCHANGED FL_DISKCHANGED: pop ax ; return address - pop dx ; get the drive number + pop dx ; drive pushax ; restore stack - pushsi ; restore stack -mov ah,16h ; read change status type + pushsi + mov ah,16h ; read change status type xor si,si ; RBIL: avoid crash on AT&T 6300 int 13h - - mov al,1 -jncfl_dc_ret1 ; cy==1 is error or disk has changed - - cmp ah,6; ah=6: disk has changed - je fl_dc_ret - dec ax ; 0xFF on error - -fl_dc_ret1:dec ax -fl_dc_ret: cbw popsi -ret + sbb al,al +jncfl_dc_ret ; CF=0: disk has not changed + cmp ah,6 + jne fl_dc_ret ; 0xFF on error + mov al,1; ah=6: disk has changed +fl_dc_ret: + jmp short ret_AH_0 + +; +; int ASMPASCAL fl_read (WORD drive, WORD head, WORD track, WORD sector, WORD count, void FAR *buffer); +; int ASMPASCAL fl_write (WORD drive, WORD head, WORD track, WORD sector, WORD count, void FAR *buffer); +; int ASMPASCAL fl_verify(WORD drive, WORD head, WORD track, WORD sector, WORD count, void FAR *buffer); +; int ASMPASCAL fl_format(WORD drive, WORD head, WORD track, WORD sector, WORD count, void FAR *buffer); ; -; Format Sectors -; -; COUNT fl_format(WORD drive, WORD head, WORD track, WORD sector, WORD count, BYTE FAR *buffer); -; -; Formats one or more tracks, sector should be 0. -; -; Returns 0 if successful, error code otherwise. + +; Format tracks (sector should be 0). + global FL_FORMAT FL_FORMAT: -mov ah, 5 -jmp short fl_common -; -; Read Sectors -; -; COUNT fl_read(WORD drive, WORD head, WORD track, WORD sector, WORD count, BYTE FAR *buffer); -; -; Reads one or more sectors. -; -; Returns 0 if successful, error code otherwise. -; -; -; Write Sectors -; -; COUNT fl_write(WORD drive, WORD head, WORD track, WORD sector, WORD count, BYTE FAR *buffer); -; -; Writes one or more sectors. -; -; Returns 0 if successful, error code otherwise. -; - global FL_READ -FL_READ: -mov ah,2; cmd READ -jmp short fl_common - + mov ah,5; format track + jmp short fl_common + global FL_VERIFY FL_VERIFY: -mov ah,4; cmd verify -jmp short fl_common - + mov ah,4; verify sector(s) + jmp short fl_common + +
[Freedos-kernel] bug?
Hi!
In main.c:init_device() driver counted as system console if its
attribute word contains only ATTR_CONIN bit. Isn't there should be both
ATTR_CONIN and ATTR_CONOUT bits set? Also, what prevents for one device be
both system console and clock driver? Also, ATTR_CONIN bit checked without
ATTR_CHAR - isn't it should be checked? So, I suggest, instead:
__O\_/_\_/O__
if (!(dhp->dh_attr & ATTR_CHAR) && (rq.r_nunits != 0))
{
dhp->dh_name[0] = rq.r_nunits;
update_dcb(dhp);
}
if (dhp->dh_attr & ATTR_CONIN)
LoL->syscon = dhp;
else if (dhp->dh_attr & ATTR_CLOCK)
LoL->clock = dhp;
_
O/~\ /~\O
should be:
__O\_/_\_/O__
if (dhp->dh_attr & ATTR_CHAR)
{
if (dhp->dh_attr & (ATTR_CONIN | ATTR_CONOUT))
LoL->syscon = dhp;
if (dhp->dh_attr & ATTR_CLOCK)
LoL->clock = dhp;
}
else if (rq.r_nunits)
{
dhp->dh_name[0] = rq.r_nunits;
update_dcb(dhp);
}
_
O/~\ /~\O

Re: [Freedos-kernel] Re: LBACache test results
I only used Interlink on FAT16 drives for the tests. True, InterLink does not support FAT32 because FAT32 didn't exist when InterLink was made. However, on normal MS-DOS, if you run InterLink/InterServer on a FAT32 drive, it won't crash or suffer data loss, it simply reports the drive as 268 MB (doesn't matter what size it really is), and the drive will be inaccessible on the other computer. > > If I recall correctly, Interlnk never had FAT32 support, so I hope C: isn't FAT32. > as alternative to FD(X)XMS, we now use HIMEM.EXE , included in the EMM386 package. > > ftp://ftp.devoresoftware.com/downloads/himem64.zip [22-04-2004] > > is probably most recent. > > Bernd > > > --- > This SF.Net email is sponsored by the new InstallShield X. > From Windows to Linux, servers to mobile, InstallShield X is the one > installation-authoring solution that does it all.

[Freedos-kernel] A pagina Negra do Cristianismo
Title: A PÁGINA NEGRA DO CRISTIANISMO -
A PÁGINA NEGRA DO CRISTIANISMO - 2000
ANOS DE CRIMES, TERROR E REPRESSÃO
Enrico Riboni
"Acreditar num deus cruel, faz um homem
cruel."
Thomas Paine
Prefácio
Há
cerca de 2000 anos, nascia na Galiléia um fundador de seita,
que acabaria crucificado uns trinta anos mais tarde. Algumas
de suas últimas palavras na cruz foram "Dêem-me de beber". E
só. A seita que ele tinha fundado tornar-se-ia, com o passar
dos anos, a maior de todos os tempos. Ela tomará o poder
político dentro do Império Romano, abolirá a liberdade de
religião, depois ajuntará montanhas de cadáveres: os seus
membros massacrarão milhões de "infiéis",
"hereges",
"feiticeiras" e outros, depois se matarão entre eles
próprios, levando a Europa às guerras mais ferozes que ela
conheceu. Um passado destes poderia incitar à modéstia, mas
os cristãos reivindicam, pelo contrário, o monopólio da
ética. Proclamam que adoram o Deus único, que deus é "amor",
e se consideram melhores que o resto da humanidade.
Única
ideologia capaz de dividir com o comunismo e o nazismo o
pódio dedicado às ideologias mais mortíferas da história
humana, o cristianismo mantém-se uma ideologia dominante em
muitos países ocidentais, como o "gendarme do mundo", os
EUA. Chegou a hora de abrir o "Livro Negro do Cristianismo:
2000 anos de terror, perseguições e repressão", que resume
algumas das piores atrocidades cometidas em nome dessa
ideologia que pretende promover o amor ao próximo.
Ano
um
"Os deuses
não estavam mais, e Deus não estava ainda."
O Império Romano garantia a liberdade de culto. O ateísmo e
a razão dominavam. É nessa época que nasce um sujeito que,
segundo dizem certos judeus, perdeu o juízo porque leu o
Tora demasiadamente jovem. Ele funda uma seita que visa
proibir o culto dos outros deuses, exceto o seu. O sujeito é
finalmente morto, mas a seita se expande com o êxito que se
conhece.
O
culto da personalidade do fundador da seita atinge, nos
cristãos, um nível que mesmo o estalinismo não conseguirá
igualar: o fundador é proclamado "verdadeiro homem e
verdadeiro Deus", ("Deus-Homem", em linguagem comum).
Os que
duvidam disso são proclamados imediatamente hereges, e
sofrerão mais tarde os raios da Inquisição. A partir do
século IV da nossa era, começará o assassinato dos
não-crentes pelos cristãos.
