Congratulations on the reflash. This eliminates one variable.

I'm now at the point of wondering just where configuration for video originates. If it is not changed by flashing BIOS or clearing non-volatile RAM, what you are seeing ought to be the behavior described in the manual. (Could the problem be with the voltages chosen by the jumper for the LCD (J VLCD), even though you are not using an LCD? I'm getting crazy ideas.)

Simply having a 75 Hz vertical refresh doesn't disqualify this from working with many common monitors. Looking back over the thread I don't see mention of the raster you think it is trying to use. An unusual raster could be one problem, though I can't imagine why it would be using anything unusual if it has been reset to factory specs.

Another possibility has to do with the definition of sync signals. Some devices running off vga ports require a small amount of added logic to extract sync signals which are supplied separately on other devices. Sync levels may also vary. I remember a battle with one using "sync on green", (though the details have become hazy.) When this fails the monitor typically says there is no signal at all.

What happened on a number of those Intel 810 chips with shared video RAM was that the behavior changed with different RAM timings. You may need to find actual 333 MHz DDR DRAM. I have one machine that requires this, 400 MHz DDR may be better, in some sense, but not if the stupid thing blindly follows the timings in the SPD.

Ram that came with it is DDR400. Ram that's in it now is spare DDR333.

It has a Winbond chip on it. Typically these are "super IO" chips that provide little extra features, like parallel ports and floppy drives, where they'd otherwise be unavailable.

I'm beginning to suspect that the config is stored on the Winbond chip.

I'm pursuing a two-phase nearly-sure-to-fly solution right now. Phase I, take it to the techno-wizard at the local computer shop. Talking to him teaches me things -- and I know a fair bit about computers. If he can't fix it, I'll be quite surprised -- but then it's onto phase II. That would be a cobbled-together riser card for this board, and a PCI graphics card. The board can't set the card's frequencies, I don't think ;)

Yes, the board has PCI. No, it's not a slot. It's a cardedge connector, exactly the type and pinout you'd find on, eg, a PCI sound card. All Commell did when they designed this board, was to ensure one would need a slot-to-slot riser. You can't get those on eBay, so you'd have to get one from Commell.

Or not. Take one PCI two-slot riser, keyed appropriately (I'm using a Dell PCI-X riser cuz it's as close as I can get -- the differences are minimal), and insert the computer in one slot. Insert a flexible PCI riser (yay for ribbon cables) into the 2nd slot, and insert the graphics card into that. As long as the two-slot riser is just wires, it'll fly (ones with "bank-switching circuitry" --I've no idea what that is-- won't work here).

Any chance of getting an oscilloscope onto the hsync and vsync pins to confirm timing?

Heck no. I don't even know anyone who has an o-scope. BUT --

I took the board (and a few necessary peripherals) to my local tech shop. The guy there should've been named Mister Wizard by his parents -- he got it (almost) fixed. I can use a screen with it now, correctly, as long as I'm in text mode. There's some graphical config issues that need sorting out, but I can get that working in the BIOS as long as I don't muck anything up further along the way.

...come to think of it, Mister Wizard might have an o-scope. Not sure tho...

He did an lspci -nn for me while I was there and gave me a hardcopy of it. I'll type it back up and post it when I can -- I've got some household crunk calling my name right now so it'll be probably later tonight (I'm on US Eastern time, if that's any help).

Here's the results of that lspci -nn command ;) this is typed up from a sheet of paper; I'll gladly scan the sheet if there's any confusion.

I'll note that this is using Mr Wizard's own homebrew linux distro for his own tech-service needs (he does own the tech shop, after all!), so I'm not sure what version of lspci he's using or if that even makes a difference.

I'm going to go make dinner now, and then afterwards I'll muck around with the board some more, see if I can figure out what's making the screen want to dodge graphics mode... any insight you folks can provide is of course quite helpful!

The last two posts were done without any home monitor testing.

I'll be going back to the shop tomorrow -- I still don't have a working display on any of my screens at home!

Be sure to post the outcome, whatever it is. If the Winbond chip is doing this that would be unique in my experience.

Getting a stable video text display at the shop, but not at home, simply means your home monitors lack the particular video mode necessary.

I had thought about that riser card idea when I saw the edge connector, but held off until less wild configurations were exhausted. I'm convinced you will get this to work very soon -- one way or another.

I've given up on making my home monitors work with the card. I think the refresh rate --or whatever config is messing with this-- is hardwired.

Fun.

I have a PCI graphics card, and a riser as well. No, not the Commell-sponsored one. I have a quote into a Commell distributor (Global American) to find out how much that will be. If it's too much I'll ask for photos. If they won't, I'll ask Commell for a datasheet on it that includes pinouts.

Or maybe mis-wired? Could it be an open circuit track on vsync or hsync? Or in the monitor cable?

No.

It works on the monitors at the tech shop just fine.

Tech shop dude won't give me his monitors -- the one I've been using is actually a CRT that someone had purchased but not yet picked up. It was his suggestion (not mine) to use that monitor, and I assume it's fairly bulletproof.

My screens are as follows:

2x eMachines (branded) eView 17F2 CRTs (flatscreen, 17")
1x Samsung SyncMaster 510MP (attached to Mom's desktop so not always available)
1x Samsung CVL-4955 (from 1991)

That's it for now -- I've another LCD that I rescued from the tech shop's recycle bin, but I'm not using it until I replace the busted capacitors on the power supply board.

Since the 510MP screen can go up to 75Hz and the 17F2s go up to like 160Hz (not kidding) I'm starting to think this is just a board with a slightly addled graphics chip.

On another note, I managed to order the wrong PCI riser. It came today. 3.3v keying, which is what I thought I had until I realized I was effing blind and looking at the wrong side of the board when I ordered the thing (hint: 5v keying is towards the front of the board, and 3.3v is closer to the back where the ports are).

I've contacted the eBay seller and let them know that I'd like to get a refund... and in the meantime, a 5v riser is on its way from a different eBay seller.

I feel like a total moron for that one. Should've realized something was up when I did a test fit (no power of course) and the graphics card was upside-down but the motherboard was right-side-up. Whoopsie.

I think I'll be using the graphics card from now on, instead of trying to make this insane-o board behave.

A bit more detail --

The screen at the tech shop that I've been using, initially only worked in text mode -- graphics mode would make it go to "this isn't a recognizable signal so I'mma take a nap now" mode. I switched a setting in BIOS (forget now which one) and it worked in graphics mode... but...

Tech shop dude didn't have a PS/2 splitter. This board has one PS/2 port, with the pins that wouldn't be used for keyboard clock/data signals used as mouse clock/data signals. A very common arrangement, that, found on elderly laptops and other small boards quite often.

I don't have a splitter either.

So I was using a PS/2 keyboard and a COMport mouse. I had a Puplite5 CD with me at the time, and it refused to recognize the mouse -- it would go through xorgwizard or to xvesa just fine, but the cursor wouldn't budge.

Mouse is known good.

I've ordered the PS/2 splitter from eBay as of yesterday. Should get here sometime next week -- it's being sent cheap, meaning slowish, meaning First Class Mail.

BTW, the USB ports --all two of them-- are on a slightly strange header. It's standard except for the pitch -- most headers are 2.54mm / 0.1" -- this one is 2mm pitch with smaller pins, so a regular dongle won't fit the header. How wonderfully special :roll: I have someone on my other forum making me a USB dongle, but it's not here yet.

I broke down and ordered the Commell-issue riser from a US distributor named Global American Inc. -- they are quite friendly and helpful! The other official US distributor of Commell products is BWI (Bill West Inc) and they were just shy of rude to me on the phone, where Global American was as helpful as they could be (which wasn't much, but it sure wasn't for lack of trying!)

It cost $12.50 or so, plus a ridiculous amount for shipping because Global American is a UPS loyalist :roll: I could put a stump speech up here about the Postal Service vs other carriers, but I'm not going to waste my keystrokes with that. Everyone who's going to have an opinion on the matter already has one.

So that will be here sometime in the evening tomorrow. (UPS Ground isn't usually this fast... dunno what's up with that.)

Then it's time to test my PCI graphics card. Fun!

Just opened the box with the PCI riser in it, from Global American. I don't know how they can get away with charging $25 normally for this, PLUS the $14 and change shipping.

I was lucky -- I knew about a British company selling the same thing for eight quid. Global was willing to price-match, but $12.53 is still a bit much for what would cost $5 on eBay if it was available there.

For those interested, a half-pound (if that) box from New Hampshire (Global American) to North Carolina (me) cost $14.11 via UPS.

All of that said, I'm about to fire it up and see what happens.

@Yogi -- I'm pretty sure I said this in an earlier post of this thread (could be wrong -- a quick look back and I can't put my eyes to it)...

But I really want to stick with Puppy. I haven't used any other Linux in YEARS. Like two. (When I did, it was Ubuntu. No thanks!) I feel at home with Puppy; it's very familiar. I don't get that anywhere else, and I don't want to have to start over with another distro. Puppy is good for my health :lol:

It probably sat on a shelf in a warehouse for years. Warehouse space isn't free, and neither are people competent enough to find that old part, box it up and ship it to you. Be happy that someone had what you were looking for, that it was correctly entered in an online catalog and that it was sent to you without mistake and in good shape. :)

Fair enough.

By the way, folks...

IT'S ALIIIIIIIIIIIIIIIIIIIIIVE!!

Proof of function is attached. I'm using Puplite 5.0 here.

Be warned: my biggest talent is to turn anything into a blurry mess using only a camera :P

Current system specs --
Spare 12v 60w power brick (AC-DC adapter -- sorry guys, it does not make music)
Commell LE-370Z / LE-370CM6 Motherboard (two names, one board, no identity crises somehow)
Celeron M ULV 600MHz, integrated
1G PC3200 RAM @ 266MHz (board is downclocking for no good reason)
PNY Verto FX5500 PCI graphics card
random spare laptop Combo Drive (optical drive) -- no HDD yet!
random spare 50mm fan (heatsink is intended to be fanless, which is very very stupid!)

Screen at the moment is an eMachines-branded eView 17F2 CRT. Very heavy :shock: but very functional!

I'm using the nv driver included with this version of Puplite. I guess "nouveau" was the one that was full of bugs and eventually dropped?

A note about the fan -- when idling, fanless, the temp is around 50 C. (The chip is rated to 100 C -- you can boil water with it!) Right now, with the noisy-but-effective fan... Puplite5 reports 15-16 C. I think I'll keep the fan :wink:

Also, considering Puplite took its sweet time loading into RAM... I think I don't want to bother with trying jejy69's GNOME232 Puppy. No, I can't add more RAM or faster RAM -- the board really only goes up to 1GB and PC2700 (333MHz) speeds. Not sure why it's downclocking to 266MHz ( = PC2100 RAM) when the stick in there is PC3200 ( = 400MHz)... but it is. Hmmm.

Tried a copy of tigerpup that I got from rhadon (thanks dude!) -- I get a consistent kernel panic. (Something must be scaring the corn inside :lol: )

I'll test that ISO another time on another system.

About to try PAW RC2. Next will be Racy 530 unless it's PAE (I don't remember).

EDIT: I think my CD drive needs a lens clean :( I'm gonna go do that and report back what happens. Also Racy 530 is PAE so no-go :(

Have you checked the settings in the bios to see whether you can set a specific ram clock and/or timing? Your ram setting(s) might be set to "Auto" in which case you might be able to select "SPD" serial presence detect. If so, this could give you the proper configuration, because the bios may detect additional info from the ram module.

BTW are you going to try Wary on this machine?

I'll try Wary later ;) Want to see if I can get Akita working, at least.

I'll see what I can do about SPD. That's something new to me -- but it sounds safe to try, so try it I will.

EDIT: didn't realize I had wary 5.3 archived. Burning a CD-RW of it shortly -- let's see if a lens clean fixed my drive!

Known-good (previously used) CD-R of Wary 530 produced: same exact symptoms as the other four or so attempts.

Let's try cleaning the drive in the Commell test-rig then ;)

EDIT: SPD is enabled already, BTW -- the other choice is manual settings. No thanks!
