Can anyone tell me if it's possible to activate "vesa modes" without using v86 mode (via ports for example ??).

also, can I use V86 mode before implementing multitasks in my OS ??

1. if you wite a driver for your card. (and every other card that is supposed to be supported.)
2. i think so..

ad 1: as christoffer has stated...

ad 2: you need multitasking up and running ere you even dare to think about building the vm86 subsystem for it uses the quite usual task switching mechanism to save states of the virtual 8086 machine - whilst being in protected mode. This is, because you have to load a separate image containing the 16 bit code into memory - say you build a process of its own which is responsible for all the bios calls. But beware, it is not the most performant solution for each and every int, push, pop, in, out instruction traps into general fault handler and in consequence into the vm86 handler you have to provide.

hope this clears some. search for tim robinsons vm86 tutorial. Thats a good one.

@bubach: hej! hur mar du?

[bubach]

Ok..

swedish: tack, bra. sj?lv d??

How are you? - Thanks, fine. And yourself?

Dudes, it isn't too polite to switch locales without providing the "C" locale - erm, English translation.

@solar: as if we needed the holy grail held beneathe our nosen to confess whatever slight sin we might have commited ... ];->. I enjoy talking in foreign tongues *sfg*

@bubach: tack, mycket bra. solen skina (not sure 'bout spelling, never seen it written). ... (for solar: thanks, very good. sun shines. *gg* And no, we weren't calling names)

[bubach]

#ifdefined __swedish /* is this correct? */
extern "Swedish"
{
Man brukar v?l skriva/s?ga: solen skiner.
Solar: Ska genast sluta upp med det..
}
#elseif
U usally say/write: the sun shines. (he wrote something like: sun shine, hard to translate bad grammar )
Solar: I will stop with that (genast.. hmm?).
#endif

@bubach:

I'd do it this way:

#ifdef SVENSKA
Jag bara liten prata svenska.
#else
I just speak a little swedish.
#endif

In Ljungby they say for 'skiner' something like 'chwina' or 'hwina'. It's not recognizeable for me. I didn't know the *written* word correctly 'til now.

Stay safe

this 'politeness' thing for some small conversation ... *grrr*stalking off not being amused*

I think it is better to set VESA up in real mode,Then when in pmode ,and need to swich modes, Swich to unreal mode,
Swich mode then swich back to pmode.
But then my OS is a bit different (eg runs in ring0,nopaging)
Even in VESA 3 you need to use 16bit pmode .
