Intel Says Farewell To PCI Bus
KingofGnG writes with this snippet from Sir Arthur's Den, which will make my desktop computer sad: "Soon another technology that in past years dominated the always changing universe of computer hardware will bite the dust. That's the decision by Intel, the merciless executioner of standards that the company itself imposes on the market. In upcoming months it will end official support for the PCI bus. Developed by the chipmaker in 1993, the PCI Local Bus standard was implemented on all motherboards for x86 and compatible platforms until 2004, the year it passed the baton to the younger and faster PCI Express technology."
Now what am I supposed to do with my Voodoo II video card?
Any Intel motherboard you buy will have a chipset with Intel GMA graphics on it. Virtually every GMA in current production, from the GMA 950 in netbooks to the four-digit GMAs on desktop and larger laptop PCs, is at least as powerful as a Voodoo3.
Back when they started dropping ISA support, I had to hunt a bit for a board with ISA support. Things like sound cards, modems, COM / LPT port cards, and so on all came on ISA cards. The couple of desktops that I've used only had one PCI card between them - a network card because there weren't drivers for the on-board one. It's much less common to have a collection of PCI cards than it was to have a collection of ISA (or EISA / VLB) cards to move to a new machine. Graphics cards are about the only thing that you regularly find as expansion cards, and these are typically upgraded at least as frequently as the motherboard anyway.
PCI is now more of a way of connecting the chips on the motherboard than a way of connecting daughter boards, and as such it's far less traumatic when it is replaced by something newer. Aside from driver developers, few people care what interconnect is used between two chips on a motherboard.

I wasn't too happy that Intel axed the parallel port, but I could get cards/USB adapters for that. Now they axe PCI? I still have a Soundblaster X-Fi, its likely the last PCI card I'll ever buy.
This will lead to headaches for embedded and industrial system users, most of them are now just moving from ISA to PCI based solutions. There were a few P4 motherboards with ISA slots for that market even.
Number of buses that have been killed off during the years is considerable:
And those are only the ones I can come up with out of my head.
If builders built buildings the way programmers wrote programs, then the first woodpecker would destroy civilization.
Can we get rid of PS/2, VGA, parallel, and serial ports now, too? Hell, let's axe DVI in favor if HDMI while we're at it!
Oh, and can someone tell the shitty mobo makers to stop requiring MS DOS floppy disks to flash their BIOSs?
A slashdotter who didn't build his own computer is like a Jedi who didn't build his own lightsaber.
I'm just getting used to these new fangled AGP cards and their single connectors. I feel so much more secure with the dual connectors of my VLB cards....Maybe if I saw the boards in half they'll work in my new PCI-based motherboards. What do think? They fit, but all I get is sparks and a strange smoking smell....
This seems like a fairly minimal matter.
Intel is shaving a few more pennies off the implementation cost for boring business boxes that will see no expansion at all, gamer boxes that will see no expansion beyond a so-new-the-solder-is-still-warm graphics card, and your basic home-user "everything-on-motherboard" use cases.
Given the availability of PCIe to PCI bridge chips(both ones for cheaply retooling a PCI design into a PCIe design, and ones for hanging an actual PCI bus off a PCIe bus), motherboards to accommodate PCI cards should be available at a fairly modest premium for another 5 years, and at an industrial/embedded/specialty premium for another decade or two....
Time to get a PCIe PCI controller card.
From TFA:
Intel PCI-free chipsets expected to be unveiled are H67, P67 e H61, they will implement the new LGA1155 CPU socket (which would be a pin less than the current LGA1156), will support 8 independent PCIe 2.0 lanes, Serial ATA connections at 6 Gigabits and 14 USB 2.0 ports. Just to be clear, these chipset are targeted at the consumer market while the new chipsets designed for the enterprise market (Q67, Q65 e B65) will continue to support the PCI bus.
So, Intel says farewell, except that it didn't.
Even if they were, if there's money to be had, I'm pretty sure someone will carve some silicon that motherboard manufacturers can use to bridge PCIe with PCI further downstream from the chipset.

Out of curiosity, I was looking for motherboards that still support ISA, and apparently there's still a market...
This ATX board I found, supporting C2Duo/C2Quad processors, has ISA, 4x serial, parallel, FDD, PS/2 mouse & keyboard, etc., in addition to dual gigabit Ethernet, RAID, SATA, PCI-Express x16, PCI, HD audio, DDR2, etc.

Number of buses that have been killed off during the years is considerable:
And yet, the short bus isn't killed off, and it continues to grow it's user base.
Freaky. I wonder if the manufacturer provides driver support for Windows for Workgroups and OS/2 warp...
Micro Channel wasn't killed, it committed suicide.
"The ferrets, they're every where I tell you!"
or any other chip maker willing to continue supporting PCI for a few years while the transition away from PCI finishes up.
You must not have done well at sawing the board in half. At the very least, you shouldn't be getting sparks. The worst you'd have done is sever most of the connections on the card. Not having electricity making a complete circuit isn't the same as a short circuit.
You must not have sawed many boards in half. I find that many of the traces end up dragging into other traces, and much of the time there are ground planes in there that get bent into other traces. Don't critique another person's board sawing when you clearly haven't sawed many boards of your own.
Each processor would proceed sequentially as if it had been better for them not to rise against Saul.
Wait until you need to talk to something that cares about timing.
It's actually made in Kentucky using the same design as the Model M. However, it's still not the same IMO; the plastic is crappier and the key feel not quite right. I also had all kinds of problems with mine not registering keypresses correctly and returned it, and bought a real Model M on ebay.
I remember VLB and ISA as well. In fact my first gamer rig, with its upgraded to the max 100Mhz Pentium and 16Mb of RAM is STILL running 5 days a week at a local lumber factory running a custom column lathe with an ISA card and DOS 3. I thought the guy was gonna break down crying when I said "Yeah, I think I got a couple of old ISA PCs".
Hell just a few months back I sold an old S3 12Mb PCI card, to a guy whose onboard had fried. I called him a week later to see when he wanted me to order him a more modern card and he said 'Why Bother? This card runs my business software just fine, and Windows 2000 is rock solid stable with it, so I'll just stick with it.'
That is why you should visit your local mom&pop PC shop every once in a while. Think of us like a giant flea market of PC parts of all ages. We're usually bored, so just come in and bullshit a little while and we'll be happy to let you rummage through the bins, you never know what you'll find!
As for TFA, has AMD announced they will follow suit? It sounds like another way for AMD to differentiate their product, as there are plenty of folks out there still using PCI (prosumer audio especially) and an AMD 4 or 6 core CPU will be more than fast enough for those tasks, and be quite affordable as well.
ACs don't waste your time replying, your posts are never seen by me.
i think intel prefers binary...
People, what a bunch of bastards
...that Intel was the only manufacturer of motherboards out there.
Sure they're heavy hitters in the field, but if enough people and companies start buying AMD so they can use their 'legacy' PCI equipment in a native PCI slot, this could get interesting...
I know of a company that had to switch laptop suppliers simply because the ones they had been using stopped supplying DSUB serial ports, which the company needed to interface with industrial monitoring and test equipment. The so-called USB / serial port adapter dongles didn't work worth crap for the equipment they were trying to interface with: they needed a native serial port. Yet they could still get the pretty-much-useless firewire support in just about every model...

So we still have PCI Express for video cards, but whats going to be the replacement bus for other cards (sound cards, wireless network cards, additional Hard drive interfaces, extra USB ports, and custom stuff?
There is also, basically, an ISA bus on your motherboard; in the form of Low Pin Count bus. As a matter of fact...PCI -> PCIe have somewhat similar relation to the one between ISA -> LPC. Roughly the same logically, as far as software is concerned, but implemented using less parallel approach. So your "using pci-e for some of them is a waste of lanes" is probably unjustified.
On board sound might be PCI based logically, but it's partly integrated into the chipset. The "audio chip" you see on a motherboard is often little more than a codec, not sitting on PCI anyway. Similar with Ethernet PHY. Super I/O and BIOS sits on LPC. And "main" chipset often sits on PCIe already.

You might want to tell the military VME is dead, They still use it heavily on ships, helicopters, unmanned drones, ... Compact PCI made some inroads, but no where near replaced VME. Looks like VPX might have a chance at seriously challenging VME, but it will be a long time before VME is dead.
Thanks, you had to go and remind me that my computer is OLD... Holy crap! I've never had a workstation computer for 6 years and still used! Will wonders never cease. Thanks Linux!

If your SCSI array counts as "Legacy" already, you're probably better off with a SATA drive and maybe an SSD for caching/journaling, but I assume AMD's supporting PCI for a while still.

Actually, DVI and HDMI are not exactly the same thing. HDMI drops the analog DVI-A pins from the DVI connector, so it's strictly digital-only (or in other words, HDMI is the same as DVI-D and not DVI-I which is what most video cards have). Something you might want to keep in mind if you think you can be clever and chain a HDMI to DVI adapter with a DVI to VGA adapter so you can use one of PC-to-SDTV things you linked to.

"If it ain't broke, it doesn't have enough features yet"
If it predates this distinction, it is by default a DX. This is true for both 386 and 486.
This probably isn't about bandwidth, but moving forward. Sure, PCI can handle a lot of the devices, but it can't handle every device. Moving forward, we have the option to do something like we did with PCI/ASA and have two physically different slots on the motherboard, or we can move forward with a scaling interface that supports auto speed negotiation and is physically compatible at all speeds of operation. (ie: put a PCI-E 2x card into a PCI-E 16x slot and it'll work.) This offers more flexibility when building out systems for different types of users, and takes the next step forward to give hardware with the new design a longer life. (ie: If PCI had been scalable in the same way, all those PCI cards would still be worth something, as would those ASA cards if they too had been compatible in the same way PCI-E is.)
One time I sawed off the back of a PCI-E 8x slot on my motherboard and put a PCI-E 16x video card in, sticking clean out of the back of the slot, and it worked like a charm. You just can't do that kind of thing with ASA and PCI.
