PSX DTL-H2000 HELP!! :-(

Sorry. I did not see that.

Well, how come when I had my H2000 all plugged in, all of the PSY-Q applications I tried did not work?
The board was invisible.

Or am I not getting the point. Do I need to just update the image?
But how can I if I none of the programs can find it??

 

EDIT: What is it with the forum software removing newlines?

As I wrote, I do not know whether this is even an issue with the DTL-H2000. All I know is that it certainly is for the DTL-H2500 (I spent three days in firmware update hell trying to get that thing to work). You should check your SDKs whether you can find a different EPROM image for the H2000 card.

If you find PSYQ and DECI images for the DTL-H2000, you could try them. Again: I do not know whether such images exist or, if they did, whether they could solve your problem. My sets of DTL-H2000 always worked out of the box (granted, one blew up, shorted the mainboard and prevented the PC from starting ever again until replacing the F701 fuse, but you get the idea).

As the DTL-H2000 card does not have an update facility (it is EPROM-based, not flash-based), you would need to go the old-fashioned way to exchange the BIOS: physically remove the chip (its socketed ), then either get another one of the same type (recommended) or re-use your existing one (NOT recommended), erase under UV, burn correct image, re-insert and hope for the best.

 

The EPROM is stored on the CPU2 board. I am not plugging this in because Ghost told me that the H2000 (CPU1) boots with the coloured bars fine by itself.

 

Ah, okay. I never tried to use one of the boards alone. I'm surprised that it is expected to work, though; I'd think the inter-board SCSI (?) bus doesn't like this configuration due to missing termination.

 

So, it is in fact faulty, yes?

I mean, I will look up some of the IC's datasheets and see what they are, but as long as there is no EPROM based chip on the CPU1 board, it must be faulty.

 

I don't know. What strikes me is you wrote you have just one board (PIO2) plugged in, and expect it to show anything meaningful. I also read through all of Cyberghost's post, and couldn't find one saying an isolated PIO2 board produces the test screen. He wrote that the test screen is shown even during boot, but I'm sure he had both boards plugged in... I would expect that, after power on, the GPU just sits there and waits for commands for the PS1 CPU. The CPU2 board would then run a simple program that displays the color bars via normal GPU commands, then halts and waits for commands from the control PC. But I'm just guessing...

Correct me if I'm wrong, but I think there is no "CPU1" board. The DTL-H2000 consists of two boards, labelled CPU2 and PIO2, respectively.

 

Cyberghost told me this in a PM. Sorry. I did not mention that.

Uh yes. CPU2 and PIO2.
I thought it was CPU1 and CPU2.

 

I don't see how you will get color bars pattern on a system that is without it's bootstrap rom.

 

Neither do I, but it does as Cyberghost says.

 

Well I do not know where to start the debugging process. So many problems and I am confused now.

Where should I begin to find the problem.
Should I try it on the 386 based system first (the older motherboard)?

 

I got the board for sale in the marketplace thread should anyone want it. Meanwhile, I will TRY to get it working still. Should it work, I may end up keeping it


UPDATE
Here are some images of the motherboard I will try:
Gigabyte AB-PT5: http://psio.com.au/images/mainboard/R0013202.JPG
Very rare, and very hard to find. I got this from my principal back when I was in year 3/4 and I believe it had a 100 MB HDD, a parallel header over ISA that also gave IDE, serial, FDD and other connections. I do not know what CPU it had, but my guess would be a 3/486. I may need to find the dip switch settings should it fail to boot :S





Q1) What is this RAM? (I think it is SIMM)
Q2) -





Q3) What is this power header called? I remember looking it up once, but I forgot what it was called.
Q4) What is the keyboard plug called?



Q5) What is the brown header used for here?



I will be putting in a 386 to keep things VERY simple. Should it work, I will swap it over for a pentium.








(Copy + Paste the question number below and please answer in a quick reply if you want. Thanks)

Q1)
Q2) -
Q3)
Q4)
Q5)

 

Q1: It's EDO RAM, probably the 72-pin variant.
Q3: It's the AT power connector: Connectors P8 and P9. Do NOT get those two reversed!
Q4: AT keyboard connector. (DIN 41524, 5-pin DIN)
Q5: I'm not too sure. :X It doesn't look like an AGP bus and I think that your mainboard is too old to even know what AGP is.

By the way, it doesn't look like a 80386 mainboard, but a Pentium-class system (It has a PCI bus, a Socket 7, the BIOS copyright date is year 1995 and it's too shiny :S).

I dug around, and it's an AMD K6-II or AMD K6-III system board.

Are you really sure that it's an ASUS mainboard? It seems like you get more results on Google if you searched for the exact same model under the dysfunctional manufacturer Abit.

On a side note: Where is Q2? =3

 

Q5) Coast socket AKA cache socket to add more cache that the processor can use.http://www.hardwaresecrets.com/dictionary/term/46

Remember back in the P1 days it wasn't embedded on the actual processor,it was ether soldered on the motherboard, socketed, or you can use a cache card later on to upgrade it.

 

Q2 has been skipped by my mistake! I added it in now as nothing. Just ignore it


Cool. Thanks for your help. Look at one of the photos. It says SIMM on the bottom of the image just under the first socket (third image).

What link for the RAM is good?

I will get this processor. Okay?
http://www.ebay.com.au/itm/SU032-IN..._Components&hash=item4ab575b82d#ht_515wt_1163

It isn't an AMD based board. It cant be. It is also not an Asus board. I believe it is a Gigabyte!


Thanks for Q5! So I dont need it to make the board run then. Awesome.

 

Socket 7 is for first-gen Pentium, compatible with AMD K5/K6 and other clones by Cyrix, IDT and Rise.
It's an Abit board, model is AB-PT5R2
Here's the manual: http://www.motherboards.org/mobot/manuals/Abit/PT5R2/
Found a mirror of the Abit ftp:
http://pross.org.uk/Abit/manual/english/pt5r2e.zip
http://pross.org.uk/Abit/bios/pt5r2/

Q1: 72 pin SIMM, you need to install those in pair.
It supports 70ns FPM or 60ns EDO modules.

Q5:256k cache on board, the connector is to upgrade it 512k.

Take the Compaq ram, don't forget you need 2 modules of identical specs (check the manual)
The cpu will do fine.

You could buy 2 of those:

32MB is obviously better than 16MB (especially if you intend to use Win98), but it might be too expensive...

By the way, the max hdd size is 8.4GB.

It seems you're in denial

 

Huh. So it isn't a Gigabyte. Thank you Unclejun
I dont think I will spend $60 on RAM to test if my board work or not. lol.

Would you be able to reccomend me a processor?
I have a spare 10 GB HDD.

Thanks again!

 

The board supports Pentium 75 to 200, so the Pentium 100 you linked will be perfectly fine.

 

Thanks.

What about this RAM?
http://www.ebay.com.au/itm/128MB128...ltDomain_0&hash=item5649af77c3#ht_1106wt_1297

 

It should work, there's a.table of possible ram configuration in the manual, look at it to be sure.

 

I got a reply from SCEE S&D in Bristol UK[FONT=Arial, Verdana, Helvetica, sans-serif]. He said that they have a DTL-H2000, but it is however in a display case (of course ).
So, being amazingly such a nice guy, he contacted SCEE S&D in London for me.

Lets hope he will help me out.[/FONT]
