I'm not exactly sure what's going on in that assembler code. What is the purpose of xor di, di ? The assembler code for the actual pixel setting above can be rewritten as follows which might be easier to understand: mov ax,0a000h mov es,ax mov di,0 mov al,80h mov es:[di],al The last line is then …

Ok, I'd try that. But honestly I have no experience with that and not the right tool. Are those chips fragile or can I do that with a thin screwdriver?

Life is strange. The other day I decided I need a GF4-MX440 for a future project. After going through my box of graphics cards I realized I didn't have one and bought a model from Gainward. Now, two weeks later, a friend showed up with a discarded PC he found. And that contained a nearly identical …

You want to write to address 0xa0000, not 0xa000. In real mode you need to split that into segment 0xa000 and offset 0. In Assembler that is done like pano69 said. I'm not 100% sure about real mode C but I think you have to construct it as a far pointer which combines segment and offset and the …

What is that inner 7.2V battery supposed to do in most laptops? Isn't that for powering RAM in sleep mode? I think the PSU in these early laptops was not efficient enough at low power draw to use the main battery and not drain it too quickly. But that's my educated guess, I'm not really into old …

Do you guys have experience with motherboards from ECS? Are your impressions good or not so good? During my search for a suitable motherboard, I came across an interesting offer (maybe). Could purchase an ECS K7S5A motherboard which already has a CPU including the Athlon 1700xp one of the CPUs that …
Re: The Joy of MMX

Pentium MMX is pretty much exactly what the name implies: a standard in-order Pentium CPU, with MMX instructions added. However, because of the extra instructions, the decoding pipeline had to be modified somewhat, which makes certain operations 1 cycle slower than they were on a Pentium classic. …
Trouble with mainboard Ipox IP-3ETI23

Recently I bought three Ipox IP-3ETI23 mainboards (S370) with P3-933 CPU. According to the seller all were once taken out of running systems, so I hoped they would all just simply work. When I first powered them on, all three greeted me with the same beeps: three long and then a alarming constant …

Did we all used to pull our desks a foot away from the wall for our CRTs to hang off? I feel like that was a thing. That Viewsonic is a pretty decent monitor. And it's showing a great demo :-D Good catch. Yes, we didn't push them close to the wall. And some placed the monitor in the corner which …

What is the definition of 'hipster' and 'scalper' in this context? I read it quite often in such discussions and while I have an idea what might be meant that somehow doesn't quite fit (for me).

the mainboard on the other hand is really essential and it is really important to pick the right parts. I am studying a lot about mainboards now to make no mistake when picking up one.

Some things keep going up, like AWE64 gold cards. There used to be a soft limit around $200 but lately it's been going up to $250-$300 which fortunately don't seem as attractive and they're taking longer to sell. Looking at the sold items on ebay I see 10 x AWE64 Gold cards sold for 120-180 Euro. …

For me one fun part is scanning through local ads and see if something interesting/cheap pops up. One approach might be simply getting what crosses the way for little money. Pretty much the only part that costs real money is the mainboard. All the rests can be reused later in case one finds a better …

There isn't a fixed value for any of this, it's mostly just luck. On day one it's $30, day 2 it's $200, day 3 it's $5. Indeed that seems to be the case with the soundcards above. I did some more research and the prices for them are just all over the place. E.g. CT 1350 were sold apx. from 15 to 130 …
