HI,
Kennt einer ein Programm mit dem ich meine in ASM und C programmierten Dateien besser im Überblick behalten kann, als sie jedesmal einzeln zu öffnen usw.. Ich suche ein Tool wie z.b. DEV-C++ (http://www.bloodshed.net/)
Danke!
Liebe Grüße

OS-Design / mem.c Asm Hilfe
« am: 20. May 2004, 19:44 »
Hi,
Hab folgendes Problem beim Kompilieren:
mem.c: In function `count_memory':
mem.c:26: Invalid `asm' statement:
mem.c:26: fixed or forbidden register 0 (ax) was spilled for class AREG.
mem.c:34: Invalid `asm' statement:
mem.c:34: fixed or forbidden register 0 (ax) was spilled for class AREG.
mem.c:63: Invalid `asm' statement:
mem.c:63: fixed or forbidden register 0 (ax) was spilled for class AREG.
Hab keinen Plan warum das jetzt nicht funktioniert! Kann mir einer von euch Helfen???
Hier die "mem.c":
#include "include\io.h"
#include "include\mem.h"
unsigned long mem_end, bse_end;
void count_memory(void)
{
register unsigned long *mem;
unsigned long mem_count, a;
unsigned short memkb;
unsigned char irq1, irq2;
unsigned long cr0;
/* save IRQ's */
irq1=inportb(0x21);
irq2=inportb(0xA1);
/* kill all irq's */
outportb(0x21, 0xFF);
outportb(0xA1, 0xFF);
mem_count=0;
memkb=0;
// store a copy of CR0
__asm__ __volatile("movl %%cr0, %%eax":"=a"(cr0)::"eax");
// invalidate the cache
// write-back and invalidate the cache
__asm__ __volatile__ ("wbinvd");
// plug cr0 with just PE/CD/NW
// cache disable(486+), no-writeback(486+), 32bit mode(386+)
__asm__ __volatile__("movl %%eax, %%cr0" :: "a" (cr0 | 0x00000001 | 0x40000000 | 0x20000000) : "eax");
do
{
memkb++;
mem_count+=1024*1024;
mem=(unsigned long *)mem_count;
a=*mem;
*mem=0x55AA55AA;
// the empty asm calls tell gcc not to rely on whats in its registers
// as saved variables (this gets us around GCC optimisations)

Hab folgendes Problem beim Kompilieren:
mem.c: In function `count_memory':
mem.c:26: Invalid `asm' statement:
mem.c:26: fixed or forbidden register 0 (ax) was spilled for class AREG.
mem.c:34: Invalid `asm' statement:
mem.c:34: fixed or forbidden register 0 (ax) was spilled for class AREG.
mem.c:63: Invalid `asm' statement:

Hab keinen Plan warum das jetzt nicht funktioniert! Kann mir einer von euch Helfen???

Offtopic / Borland Turbo C++
« am: 16. April 2004, 12:26 »
Hi,
Hab folgende Befehlszeile in Borland Turbo C++ V3.0 verwendet:
tcc -c -r- -mt -2 kernel.cpp >> NULL
Ich glaube ich weiß noch was folgende Befehle waren:
-c = Compile only
-r = Register variables
-mt = Tiny Model
-2 =
jetzt kann ich nirgendwo die Version 3.0 finden! Kann mir jemand sagen wo ich Borland Turbo C++ V3.0 herbekomme, oder mir die Befehlszeile in einen aktuellen eines C++ Compilers wandeln! Danke!

Ja, wie es aufgebaut ist schon! Aber nicht wie ich meinen Bootloader reinbekomm und das Dateisystem erhalten kann! Davon standt da nichts!

OS-Design / C Befehle??
« am: 14. April 2004, 13:27 »
Printf habe ich wie folgt hinbekommen:
;Datei ist Video.c
void printf(const char *_message)
{
unsigned short offset;
unsigned long i;
unsigned char *vidmem = (unsigned char *)0xB8000;
out(0x3D4, 14);
offset = in(0x3D5) << 8;
out(0x3D4, 15);
offset |= in(0x3D5);
vidmem += offset*2;
i = 0;
while (_message != 0) {
*vidmem = _message[i++];
vidmem += 2;
}
offset += i;
out(0x3D5, (unsigned char)(offset));
out(0x3D4, 14);
out(0x3D5, (unsigned char)(offset >>
);
}
Jetzt fehlt mir noch das "scanf" kann mir da jemand helfen??? BITTE!

OS-Design / C Befehle??
« am: 14. April 2004, 13:16 »
Neues Problem!
Ich hab mir nen Bootsector mit Assambler und Kernel mit C geschrieben und linken usw klappt alles! Nur jetzt will ich folgendes verwirklichen:
int anzahl;
printf ("\nBitte eine Integer-Zahl eingeben : ");
scanf ("%d",&anzahl);
printf ("\n\nSie gaben %d ein\n",anzahl);
Er kennt aber die Befehle printf und scanf nicht! Wie kann ich die nun mit einbinden??
Vielen Dank!

Lowlevel-Coding / Bootsector Diskettte Formatieren?
« am: 14. April 2004, 12:45 »
Das versteh ich nicht ganz! Kannst du mir erklären wie ich das zu schreiben hab! Ein Beispiel wär nicht schlecht! Kenn mich mit Assambler nicht so gut aus deshalb wäre ja der Bootloader das richtige! Ich versteh nicht wo und wie ich die Bytes auslesen soll! Und wo ich die dannach in meine *.asm einsetzen soll!
Danke trozdem!

Hi,
Erstmal Super Magazin! Echt spitze! Für die Zukunft würd ich mir noch mehr Beispiele wie eine Konsole (Weiß das es das schon im ResourceCenter gibt aber wie binde ich das ganze ein??)!!
Jetzt zur Eigentlichen Frage! Hab den Bootloader geschrieben und er funktioniert eigentlich soweit das er sagt "File not Found." Weil auf der Diskette keine Kernel.bin vorhanden ist! Wenn ich aber jetzt eine auf die Diskette kopieren will, kommt immer "Diskette Foramtieren!" Hab den Bootloader mit rawrite auf die Diskette geschrieben und wie kann ich nun die Diskette so machen das ich da auch noch Daten draufbekomm, troz Bootlaoders?
Vielen Dank im Vorraus!
