Problems installing SNASM2 PCI card

You don't understand why? Why not! Push the old technology to the limit! Besides it seems to work well in my Pentium 3!
I was very happy with that since I still haven't found a case for that 486 you sent over... :wink-new:

Plus the more modern it can be the better compatibility for transferring things back and forth between newer computers.
What I fear is that one day these older machines (Especially AT style ones) are going to have issues.
For example the P3 uses our good friend ATX PSU standard which is nearly 20 years old now (Wow!).
If the AT PSU dies in an old 486, sourcing a replacement is definitely going to be tricky.

But definitely a valid point there, try another machine... Do you have any other machines you could try the card in perhaps?

 

you tell me a 486DX4 100 overdrive CPU with max RAM push that not to ... -.- that cpu alone cost around 30€.
I Understand pushing to the limited, but P2 is wrong timeline for you MD ...
PS is P2 not MD .
Sorry but that board with the setup and the hdd i installed it was first time goal.

 

Hahaha, don't worry I haven't thrown out the machine! :wink-new:
I would like to benchmark it against my AMD 5x86 133MHz though and see who wins! :biggrin-new:

 

it is a DX4/100 Overdrive at all, and i love to spend money in it, but when i read about problems with a snasm2 on a p2 board i get ....
Skip on PS dev than you have the right board maybe, but MD on that chipset ok -.-

 

:smile-new: I get where you are coming from. I wonder if Headcrab has any other PCs lying about though... :dejection:

 

the point is spend respect on that hardware and not putting a SNASM2 on a p2 board is like putting a porsche into a ...

 

... Cheese farm? :victorious:
I'd be disappointed if a SNASM2 product wasn't made to the highest standards of the day and age and was made to be future proof! :congratulatory:

 

i try to put it on right way... made your experience. But maybe you remember im not telling you bullshit. You had the Bratwurst HDD ... ^^ Sag besser Worschtsupp ja.

 

Don't worry so much, you'll get wrinkles! :biggrin-new:
Although I guess we were warned about the Ferengi at the Academy! :wink-new:

 

Yup, another PC is first on the list to try now. I can get hold of a Pentium 75 board and chip, that might be old enough to do the trick. Now, getting hold of an AT PSU and a keyboard with that damned fat connector...

 

Hahaha, trusty old 5-pin DIN!
I've come across this really nice motherboard with AT and ATX power supply connectors.
I thought that was cool and then I saw it had both 5-pin DIN and PS/2 connectors!
I think one of my AT PSUs is about to explode... that said, the PicoPSUs are a perfect substitute with an appropriate adapter.
Keep up posted on your progress as always! :smile-new: We'll get there one way or another!

 

5 pin din and ps2 are the same for keyboards - just a different connector.

Use a PS2 keyboard and buy an adapter.

 

That rings a bell, yes I remember this from my PC repair days! Cheers, that would make it much simpler. Not that the old IBM M was sub-par in any way

 

What Jackhead is saying makes sense, RetroJunkie... I remember back in the day having problems with some ISA expansion boards on newer PCs because they had no "real ISA BUS"(there were a ISA BUS, but it was forwarded through a PCI to ISA bridge) .

Instead PCI capable PCs have a sort of hardware HUB (PCI to ISA Bridge) on the North Bridge which adds all ISA devices to the computer memory map (almost) transparently.

Yet some ISA boards would not work on a motherboard equipped with PCI slots.

It's not about the processor, it's about the motherboard chipset.

It mostly affect obscure hardware with very specific uses, like early ISA video conference cards, for example.

 

My BIOS has a lot of options for configuring this mapping, so that makes a lot of sense.

I think this is about as obscure as we can get!


Older PC is it, then.

 

Or obscure hardware like a SNASM2 card!
I just wish I had more boards with ISA and PCI slots to see if any others show the same issue as the setup Headcrab has.
How I hated my AMD Athlon ASUS K7V board... I remember it having a strange issue with SB Live cards due to the VIA chipset...
Had to settle on a Vibra-class sound card. Or was it the other way around? Meh!

Thanks for the insight though into how it all worked back in the day. I'm very glad it works on the Pentium 3 board I have here!
And I definitely am glad to have the luxury of USB on my not-so-real ISA bus! :smile-new: (Don't say fake in front of the children).

Oh that reminds me, Jackhead are you about? Don't happen to have a manual for this motherboard that was sent over do you?
There's a million jumpers and the only thing that's marked is the CPU bus speed.

Edit: Oh hai Headcrab! Didn't see you there! :biggrin-new:

 

Well I've managed to replicate your issue Headcrab on a Pentium 100MHz (P54C) on a TX Pro chipset or similar, circa 1997 / 1998.
The only machine the CD emulation card fits into and it fails to initialise the SNASM2 card just like yours.
It should work first time on those, which means this PC needs to find a new home and you need to get that PC!

486 - SNASM works fine.
P1 - SNASM stops working.
P2 - SNASM still not working?
P3 - SNASM starts working again.

So at least on my Pentium 3 chipset they fixed whatever was botched up back in Pentium 1 days.
Do let us know how you get along with hunting down another PC to give it a go on. :smile-new:
Now I need to find a home for this non-SNASM2 compatible Pentium 1! :suspicion:

Edit: Image added of the error I was getting on the Pentium 100. (Why does ImageShack corrupt my photos so?)

 

Awwww yessss! I was hoping it was that simple. I'm getting excited about this again!

I'll hunt down a new PC ASAP! Thank you so much for testing

 

Haha, no worries! Pure chance I managed to get the PC up to my place. Anyone need a P100 and motherboard?
Guaranteed not to work with SNASM2 cards! :friendly_wink:
Looking forward to some new entries on your website too! Keep us posted! :congratulatory:

 

Well now this is an interesting change.

I have been trying to get all my kick ass full-length-and-then-some ISA cards (such as Gravis and CD Emu card) and was having no luck.
Either the IDE controller was too long, missing a secondary connector or the sound card was too long or I couldn't work out the CD-ROM settings...
But after all that, I pulled the Pentium 1 100MHz TX Pro board out of my misc box of bits and disabled everything I could.

Apparently I didn't disable the "internal cache" on my last attempt. :livid:
And this is exactly what was preventing the SNASM2 card from initialising.
Lights blink back and forth on the SNASM2 card when internal cache is enabled and throw up something along the lines of card cannot be initialised.
With it disabled, it sets up perfectly!
And now it is on a socket 7 board, cache on for gaming, cache off for developing! :applause:
