hi mike

why you initialize vmmngr before pmmngr? (in vmmngr initialize routine you use pmmngr alloc function)


-------
i use old kernel loader for loading kernel and initialize vmmngr after pmmngr then i doesn't have any problem with memory!!!

hi

how can i use vesa in pmode?

and have anybody tutorials or articles for working with it?

i found problem:

vmware return wrong amount of memory, it's always 2MB less than real memory, for ex:

64MB --> returned 62MB

man, the problem could be in you printf. see, itoas function returns signed numbers, you may change it (or create copy of that) just for unsigned values. I had the same problem when number of blocks was negative, but solving of that problem is changing printf function and some changes in memory bas...

problem is only in the vmware,

in bochs, returned memory is true

hi

in demo 11, memory size is alway 2MB less than real memory size. for example:

System Memory is : 512
returned memory size: 510

A side effect of this is that you can't have any local variables in a naked function.

how can i solve it?

i am workin on Demo6 and i use it for other tutors( like as pic and pit). and i cant get cpu vendor. it test it with another char* but it dosnt work

hi

%s dont work in printf function

Andyhhp:
thanks, how can i resolve this problem

The problem is solved! I modified the code to void _declspec (naked) i86_pit_irq () { _asm pushad //! increment tick count _pit_ticks++; //! tell hal we are done interruptdone(0); _asm popad _asm iretd } this is very good. how can i get extra information in this method? what is "_declspec (naked)" ...

my soulition for pic and pit interrupts: void _cdecl pit_irq () { _asm add esp, 16 _asm pushad //! increment tick count g_uPitTicks++; //! tell hal we are done ahalInterruptDone(0); _asm popad _asm iretd } and for software interrupts: void vec34(void) { _asm add esp, 12 _asm pushad printf("interrupt...
