I tried to develop a vbe3.0 driver for my "os",but failed hopelesly !!!
When I call the 'pminitialize' it never comes back !!!
Anybody has successed ? (I have a Diamond Viper 770)
Anyway,Shall I care about vbe or forget about it,it seems to me that it is a little abandoned !!
Any help is welcome !!!

Personally, dude, I'd forget about it. Very few
cards support vbe 2.0, let alone 3.0 (what's added
in 3.0, anyway? 3D support?)
I'd support vbe1.2 as a fallback if you don't have
the correct chipset support ('cuz a lot of cards
support(ed?) the vbe1.2 interface.
I'd also be inclined to support vbe 2.0, 'cuz it's
infinitely better than 1.2, and there are still some
cards that support it... but I think 3.0 is a lost
cause.
Just my opinion

Hi J.Weeks
You mean the new cards(like GeForce2 and others)do not support vbe3.0 ???
Consider that I do not want my os to run on ANY low level machine,
but most people do(don't know why wasting on TOO backward compability??)
The biggest problem is with vbe1.2 and 2.0 is that you CANNOT switch
videomode in pmode,only at boot-time when in real mode,
and switching back to real-mode and such thigs are
ugly tricks(in my opinion) that should be avoided.
Am I right ?
Anyway,If there is no other way all I can do is to create
a simple VGA driver,but i have looked at the HW docs and
seems to be a big pain (even for those 320*256 pathetic pixels) !
I still hope !

Why are you worried about switching back into
real mode? As far as I'm concerned, stay in
real mode from the start. Real men manage their
own memory.
