Board index All times are UTC. The LSe manual I have doesn’t explain what the individual Ail selection jumpers are, only where to put them for a particular processor.

I didn’t have time to save the results, but I hope to get back to it tomorrow zli I’ll have the house to myself for most of the day. For reference, I’ve attached a manual and board layout if anyone wants to take a look. The 3 jumpers to the right of the clock generator controls alu FSB.
One of my cyrix 5x chips needed 3. If I remember correctly. I can’t find any datasheets for it.

When looking at the manual, do you see what I mean about lack of any detail regarding multipliers? I also have reason to suspect this is the clock generator for the SMT Terminator.
Faster than SiS as well. If you don’t want to remove the sticker, you can usually tell if it is UV EPROM by noticing the thickness of the chip and the sandwich look to it. I’ll have to take a look at modbin, it would certainly be useful to have some control over parity since most of my DRAM modules are bit.
Besides needing to add a 3rd clock speed jumper S2 to the clock generator, I think the most difficult part of achieving 66MHz might be figuring out which jumpers are the PCI divider assuming it has one and CPU multiplier.
Then I put sticks fromm and in the machine assuming that they are FPM memory but I’m getting the same results as before. There is no material that is knowingly illegal here. Has anyone else experienced this? This site hosts no abandonware. Sure enough the memory benchmarks dropped by a pretty noticeable amount, so it does seem like the ALi chipset will indeed leverage EDO RAM when available and unlike SIS, provides a tangible improvement in performance.
This really ail its usefullness with an Am5x or Cyrix 5x The more I learn, the more I realize how much I don’t know. If anyone in the states has a spare S3 Treo64 they’d like to send I’d gratefully accept, otherwise I can hunt one down on eBay.
Return to General Old Hardware. Since I’d likely never need to use the 4V option, I could always replace the relevant divider resistor to change the 4V selection to 3. I suspect the memory performance differences may be related to the fact that you are using EDO memory, which not always means better performance in Otherwise, yep I could sneak a trimpot in there somewhere too.
I did not bother to check mine with EDO. You do not have the required permissions to view the files attached to this post. I’m looking alk to your test results of EDO vs.

I’d rather not tear the sticker off to find out I’m a stickler for detailsbut I suppose I could drop the chip into to one of my device programmers and see if they can identify the chip using the device ID bits. I could probably epoxy an angled pin header right to the top of mm1487 clock generator to add third jumper. That is the case with SiS boards anyway.
One thing to note: This board isn’t as popular as the LS there’s barely any information available. Users browsing this forum: I’d be happy run some time demos.
Thanks for the detailed reply!
