uses

/dev/mga_vid
-> and I haven't bothered with the second head ... yet!  ;-)   

I've come across most of that here though not applicable to my video card.

-> That is a good idea.  Personally I'd just use bash but something like

Learn?
I just kind of winged it intuitively.
One has to *learn* PERL?
It was my second script after the miusic CD to WAV to MLAME MP3
script.
Cheated on that one by modifying an existing script snatched from the web. 

-> most of my targetted machines such as the new system I am working on
(pure DC

for

second

-> 
-> It shouldn't need that much.  As shown above mga_vid is only using 32M
but that
-> is what is on the card and not shared memory.  Works FANTASTIC!!!

I looked at dmesg per your suggestion.
64 Meg here.
mplayer compiles this way where it hangs early in MAKE
idf set to 0xd and 4000 

->  WC> I'll look for that frame buffer figure shortly.

-> I looked and didn't see it in there anymore.  It used to say but that

when.

I am content struggling by with my Voodoo card.

-> 
-> No doubt.

I felt the need to shred the decryption liobrary as it was
snagged forom a Soviet Republic and now also communist China.
Both now safely shred to prevenmt domestic terrorism.
Still, now decrytion is troublesome :-(

->  WC> Also videolan is coming along and I just need to set a

-> 
-> Right.  I've needed to do that for a few apps.  Not many but a few. 
pkgconfig
-> stuff.

I'll get back to it shortly as it presents no real challenge.
Saving it for later for something less creative to do.

-> 
-> It is settable which makes it nice.  For ftp streaming over the wireless

(mpeg4

as my

matter.

I am a bit backwards you know.

Right back at ya :-)

It's got the ltternative beat.
