1242.0. "PowerStorm 4D60T - Texture Memory ?? Any onboard ?" by PEACHS::PEACHS::BECHTOLD () Fri Feb 07 1997 14:33

	Hello,

	I have a customer asking a very basic PowerStorm 4D60T 
question  about Texture Memory. They are as follows.

1) Does the Powerstorm 4D60T come with any Texture Memory standard ?
   On the board, without having to purchase and install the Texture 
   Memory DIMM's.

2) Is there any way via Software to determine the amount of Texture 
   Memory installed on the PowerStorm 4D60T ?

    Or do you have to physically look at the module and optional 
    DIMM part numbers etc...

Any help is appreciated.

	The PowerStorm 4DT cards come standard with no texture memory. Texture mapping still works without texture memory, going through a software rendering pipe -- with a, ummm, "noticable impact on performance". (More than 20 times slower) Software can determine the amount of texture memory installed -- the method should be in the release notes. On NT, there is a Video Configuration applet that reports this information.

	Hello, Thanks for the quick response. I see no reference to deterining the amount of Texture memory in the Open3D V4.2 Release Notes for Digital Unix. - How might one determine this ? Dave Bechtold X31216

	I actually work on the NT version, but talked to Jim Rees (one of the 2d people from the unix Here is his response... In the file /var/dt/Xerrors (or /usr/lib/X11/xdm/Xerrors if running xdm), will be a line such as this: Screen 0 Cateyes 4D60T Rev-A, 1280x1024, 102 bpp, texture 2Mx8, TrueColor-24 Alternatively, grep for "ingr" in /var/adm/messages: Feb 3 12:03:44 bluezone vmunix: ingr0: Attached 4D60T.0.0.71.0xf FB.0.0.76.20. 128.8 TP.66.1@2Mx8 The TP field indicates the texture size. Keys: 2Mx8 == 32 MB == (2048x2048x2) 1Mx16 == 16 MB == (2048x1024x2) 256x16 == 4 MB == (1024x512x2) Jim didn't mention what you'd get with NO texture memory, I expect it says OMb or None or suchlike. I've asked and I'll post any response I get here... Thanks, Keith Comeford NT Cateyes(PowerStorm 4d40t/50t/60t) Project lead
1242.4	Thanks for the Quick response :^)	PEACHS::PEACHS::BECHTOLD		`Mon Feb 10 1997 11:47`	6
	Thanks, I'll let you know if I have further questions. Regards, Dave Bechtold
1242.5	If there is no texture memory	BGSDEV::COMEFORD	There's coffee in that Nebula !	`Tue Feb 11 1997 09:57`	7
	I verified with Jim Rees that if there is no texture memory present instead of 2Mx8 or whatever that line will have "None". If you have any more questions, please ask. Thanks, Keith
