vesa mode 105h or 117h

[Keith Thompson]

Alex,

The Bank Switching hint was exactly what I needed. Thanks for the help.

Lawrence

I'm glad you got the help you needed, but in the future you're more
likely to get good answers if you ask in an appropriate newsgroup.

I am trying to access the video memory in vesa modes 105h or 117h. These
modes are 1024x768. When I try to fill the screen, I only fill in the top
75%. My question is how do I access the complete video memory? It seems this
is an issue with the 65k block, how do I access the other blocks?

memset( (char *) 0xA0000, 0x0E, 0x10000);

Lawrence

What compiler are you using?

Can it handle arrays larger than 64k?

Ciao
Giovanni

The fact he's using a physical address 0xA0000 and not a 16:16 segff pair
suggest a 32 bit compiler
to me, probably using 32 bit pmode. He's stuck at 64k unless he uses a
linear framebuffer
mode, and can have the entire video memory mapped to some offset in extended
memory.

Since the PC's memory map only has 0xA0000-0xAFFFF mapped to vga video
memory,
this is why he has this limitation, which can be overcome by what I
suggested in my answer.
Which was flamed viciously by the regs here.. oh well *sigh*

Its not actually a compiler limitation.

Do i connect to those on port 119? ok when i said groups, perhaps I should
have prefixed it with "news"

I think Mikes point was, if you want to find info on the internet, a search
engine is a good place to start.

Rubbish. Most manufacturers keep it a secret (besides intel and amd).

Have you actually checked PC Manufacturers' websites? You're talking
garbage. But in any events this is wildly offtopic ,so enough of it here.

Yes.

So I suppose the point now is that some folks are beyond help.

ROFLMAO!

Gotta love these uptight newsgroup nazi gestapo guys.
If it doesnt conform to paragraph 3.12a of the newsgroup usage
laws its a "Plonk".

Yeah, well, who gives a shit what you think? This is comp.lang.c, not
comp.lang.alexs.playground so either stick with the topic or clear off.

Actually, "Plonk" to you too. You n00b.

You called mike a noob? You bozo.

 

[Mark McIntyre]

Actually, if you want to make that big a deal with his question being off
topic please show me a newsgroup dedicated to hardware programming.

Why? Do your own web research.

 

[Mark McIntyre]

I agree with you.
Unsurprising.

Your answer was informative and to the point.

So what? I could have answered a question about motorcycle maintenance
informatively and to the point. Would that be ok in comp.lang,c?

I think your answer raised the discussion level.

How do you make that out? Except by changing the topic of the group to be
"anything c-ish , even if its actually platform specific, hardware related
or an algorithm"

Welcome to 24 hours ago mark.

All i can say is for **** sakes get over it. It was off topic
yeah goooooooooooooooooooooooooooooooooooooooooood
None of this harping on by you or anyone could have made the original
thread go away, so why bother?

stfu and move on. or perhaps, IGNORE threads that appear "off topic",
because your responses (if not related to the original question) will be
off topic too.

Do you respond to the threads such as "Buy high performance viagra
for $50"? Do you remind them they're off topic?

When you pay for my internet connection and my computer, I'll let
you decide where and what I post.

google ISNT __always__ the answer.. ever googled something you thought was
specific enough and sifted thru dozens of irrelevant search results? This
has happened to me on many an occasion, which is when I turn to newsgroups
for an answer.

Its not me that needed to do the googling, I knew the answer to
Lawrence's question. And I knew my answer was 100% correct.
So I gave the answer. What most of you idiots gave back was the
spanish inquisition, and a "how dare you post this" response. Eat a dick.

Get over it, move on.

capped.

Mark, please don't feed the troll.

Welcome to 24 hours ago mark.

Newsflash: usenet isn't instant messaging. We live in different timezones.
Some of us don't sit at the keyboard 24x7 waiting to answer posts.

All i can say

is way too much. Get a life.

IGNORE threads that appear "off topic",

no. See Jack Klein's recent posting.

 

[Mark McIntyre]

Mark, please don't feed the troll.

Still not certain he's trolling - I think he genuinely believes he can do
what the heck he likes, where he likes, and doesn't have to give two hoots
about anyone else. Such people irritate me.

But yes, I'll stop feeding.

I fail to see how that differs significantly from trolling, but let's
drop it.

RTFJF: <http://www.catb.org/~esr/jargon/html/T/troll.html>. A troll is
specifically _designed_ to provoke flames. It is not sufficient that a
poster merely have that effect out of brainlessness or personal, but
unintentional, obnoxiousness.
(If it were, many international politicians would be trolls. As it is,
most of them are definitely kooks, but not trolls.)

nah.. this isnt a moderated group, so I dont care to do so.

Then I (and most others, I suspect) don't care to read your messages
any more. Bye, now.
