Loading extra fonts (through BIOS) and seeing where the IGD stores these.

Writing to all available display pages and seeing where the IGD puts the character codes and attribute bytes.

Now until someone else comes up with a better explanation, you can investigate matters further by: It installs perfectly fine and I can actually play it for several. I have recently purchased the Inspiron E1405 with Intel GMA 950 graphics and installed and played the Sims 2. I don't know why Intel chose to not put a character code at (e) or an attribute byte at (f), but doesn't it at least bear some resemblance with the Odd/Even scheme? Hello all I have read several other messages in this forum about Intels GMA 950 cards and they dont quite answer my questions. Over are the days with cumbersome access to bit-plane 2 for font manipulation! The text video modes use a similar organization and thus the bytes at (c) and (g) are tied to bit-plane 2, meaning they represent bit patterns for the character set. In the 16-color graphics modes the LFB is organized like so: - 1st byte of bit-plane 0 Mov bx, 0010h Bus=0, Device=2, Function=0Īnd ecx, F0000000h -> ECX is linear address of the LFB To get the address of the LFB on the GMA950 you can use this code: mov di, 0018h Offset for GMADR VRAM (Total): 64 MB of Shared System Memory.

Here are the specs: Intel GMA 950: Chipset Model: GMA 950. Ok so I have a mid 2007 white MacBook that has an Intel GMA950 graphics in it. If it looks like a linear frame buffer, and if it functions like a linear frame buffer, and if it sits where you would expect a linear frame buffer, then most probably it is a linear frame buffer. Intel GMA 950 driver for Windows XP Professional. Since the bytes marked with (b) correspond to odd adresses they aren't used. (b) Not using these bytes is the inevitable consequence of the odd/even operation used in the text video mode, where 2 consecutive character codes in the host memory occupy consecutive even addresses in the display memory. (a) These byte aren't used because they match with an unused bit-plane 3 | | | | | | | | | /-> attribute byte 2nd cell | | | | | | | | / -> character code 2nd cell | | | | | | /-> 2nd bit pattern 1st ascii E una versione più veloce della GMA 900 non ha hardware decidato per T&L (Transform & Lightning richiesto da alcuni giochi). This is how the first 12 bytes of the Graphics Memory are used: /-> character code 1st cell LInter Graphics Media Accelerator 950 (anche conosciuto come GMA 950) è un chip integrato (onboard) nel chipset Mobile Intel 945GM per i processori Intel. The 1st byte of each dword matches a byte in display plane 0, the 2nd byte of each dword matches a byte in display plane 1, and so on.

When the GMA950 operates in text video mode, the Graphics Memory is organized as a list of dwords.
