First of all Happy New Year.I have bought a GVP HC8 card for my A2000.I don't have the software disk.I have install it but my Amiga does not recognised.The HDD says WB 3.1 with software.When I ran sysinfo does not find anything.
-
You don't need a disk. Once it's installed correctly you can prep the hard drive with HDtoolbox. Does it show up in Early Startup menu? What Kickstart ROM version do you have?
-
Finally its ok the card.Only the Hard disk needs format now.I have 2.05 version.
-
With 2.04 ROM you should run Workbench 2.1. Good luck! :)
-
if that HD says 3.1 and software do yourself a favor and spend the $20 and upgrade to 3.1 rom.
-
Worth updating my A2000 to 3.1 or not?

Yes. Always. :hammer:

It's easy procedure to upgrade my rev6 A2000 to 3.1 rom?

Depends. It's a socketed chip, but the rectangular (DIL) kind. Aim for the gap between the socket and the bottom of the chip.
Levering either end, gently, alternately, a little bit at a time, it should just pop out. There are plastic tools to do this, but a small flat bladed screwdriver will do the job.
Plugging in a new ROM chip (only one on an A2000) is easy, just make sure you get the notch at one end the right way. Same way as the old one was.
Make sure it goes in flat, no bent pins. If one side is a little bit off, you can put one side in a little, bend the pins in a row to line up the other set, and press it in fully.
If you do bend a pin, it can be straightened out with small pliers - again, gently.
First time it's a big deal, but it's not that difficult really. Even if you never done electronics at all.
-
Finally I bought 3.1 roms for my A2000 but when I install it refuses to boot.When I replace it with original ROM(2.04) it starts normally.
-
Weird, mine works fine with a 3.1 rom.
Are you sure what you received is functional?

Where did you buy the ROM from? A reputable seller or some fly-by-night on ebay? It's possible that you got a defective one, or damaged in transit, or by static electricity during handling. Try again, clean & inspect all pins, make sure nothing obvious (like putting it in backwards, etc.), test it on another board, if you have one. Inspect the ROM socket for corrosion (especially if you've had any battery leaks).
What exactly happens with the ROM installed (when you say "refuses to boot")?
If all of the above fail, contact the seller for a replacement.
-
I get a grey screen when its installed.I bought it for a reputable local seller which has sell many of this.Maybe I will try again...

Not unusual, typically is a loose SIMM module or ROM chip on the card.
Also, check ROM to see if has a little adaptor fitted for 32K sized GuruROM, as opposed to more typical 16K GVP ROM. Even those sometimes need an update, for removable media I think.

If not yet said, some old A2000 computers need a connect two rom's pin with jump wire.

As far as I recall, that only goes for some A500 boards. The more interesting question is now: Is this a ROM for an A2000? And which board revision are we talking about?
A3000 or A4000 ROMs cannot be used in A2000's, for example.

Very important point. There are several versions of the "A2000" out there, and while they can all be modified to rev 6, on some of the earliest versions it is a long, tough job. Most are Rev 5, but there are still rev 4 German made units out there that have NEVER been modified.

Bottom most link off that is slightly more detailed.

In all honesty - I have yet to meet an "honest trader" when it comes to selling retro computer hardware, in the sense of knowing exactly what kit they are selling. Maybe I just met the wrong people.
-

Sorry Pat, go back and check your schematics again, this information is incorrect. Rev. 6 is completely different board layout from Rev. 4. The only way to "modify" would be to replace the motherboard. :lol:
http://amiga.resource.cx/mod/a2000.html
Most boards I've seen in the US seem to be >6, I think Europe has the greater number of older boards. But that's just FWIW IMHO. ;)
-
If not yet said, some old A2000 computers need a connect two rom's pin with jump wire.
A2000 revisions below 6 can need pins 32 and 21 connecting. On the ROM connector. It's hardly a major fix.
; For the revisions 3 and 5, pins 1 and 31 must be connected to the base. To the
ROM pin 31 and connect it to pin 21. No additional connection is required for revisions 6A and higher.
If the machine is OK with Kickstart 2, it can use 512K ROM, so that does not need fixing. :)
So maybe is 1mb size 3.1 ROM. Or just broken 3.1 ROM in 512K size. What is part number on chip?
If it is 1mb ROM, can be implemented less easily with this (necessary if 3.9 ever installed on machine);

The chip says Kickstart v40.63 Amiga 500/600/2000 1993-1994 Escom AG.My Amiga is B2000-CR rev6
-
Odd, then isn't 1mb 3.1 rom compatible with A2000 rev6 512kb?
-

1MB ROM's are few and far between. Pretty much all custom jobs. I doubt this is your problem. IMHO buy a regular 3.1 ROM from AmigaKit for <$20 bucks and pop this in, see if this rules out the problem with an incorrect or defective ROM.
-
One oddity I noticed - the part no. covers all 3.1 ROMs fitted to A500, A600 and A2000 by Escom... but...
... Amigakit don't appear to sell an A600 version. They do separate versions for A500 and A2000?
http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=157
So maybe it's a pull from an old A600, an original part - but if your Amiga doesn't have a PCMCIA interface like a real A600, it won't start up. Because it's trying to initialize a port that isn't fitted?
That's another possible reason. I guess if you did it the other way around, an A500 ROM would startup an A600 OK, but you wouldn't get the PCMCIA port working in a hurry... Something like that, maybe. ;)
-

A600 ROM is listed on their page right under the one for A500/1500/2000. ;)

Finally it worked.I have new problems now.The HDToolBox can't see the hard disk so I formatted from Workbench. I tried then to install Workbench to the hard disk but still no boot..The previous owner had two partitions and the machine booted normally.Also I have not light from the front led...(when the HD working).Do I need the disk hat came with the card?Unfortunately i don't have it.
-

?

Check that the wire going to the LED is plugged into the appropriate connector on the HD controller?
-
One oddity I noticed - the part no. covers all 3.1 ROMs fitted to A500, A600 and A2000 by Escom... but...
Which is no miracle, since the ROMs of all three machines are identical. Even the A2000 and A500 include the IDE scsi.device, except that it is not used.

If these are original 3.1 ROMs without any "improvements", then there is no need to.

Somewhat bad news if people want to run an A570 with 3.1 - surely they have to cook their own ROM to remove the "new" SCSI device?
I do so hope this is the case. Because I have an A570.... ;)

Do I need the original disk that came with card to format the hard disk with HDToolBox?The HDToolBox can't see the hard disk.I've seen the icons in the Workbench normally but I can formatted the hard disk via HDToolBox.

HDtoolbox is only for prepping and partitioning the drive. You format it using the normal Workbench "Format" command (or PFSformat, or whatever, if you're using an alternative file system). If the drive isn't detected by HDtoolbox at all go back and recheck your connections, ID and termination settings, etc.

Neat toy, I wonder how one of those would work with a Vampire? :banana: :banana:

Check icon information of HDToolbox. There should be a tooltype reading SCSI_DEVICE_NAME=gvpscsi.device

You also need HDToolbox to make a partition bootable.
(or PFSformat, or whatever, if you're using an alternative file system).
That's more for experienced users. The standard Format command is ok for all file systems.
If the drive isn't detected by HDtoolbox at all go back and recheck your connections, ID and termination settings, etc.
If partitions of the drive are shown in Workbench, then the hardware is ok. It's just a configuration issue with HDToolbox.

I tried everything HDToolBox can't see my Hard disk.I don't know what to do.I tried two versions from WB 3.0 and WB 3.1

Run this and attach the report here: http://thomas-rapp.homepage.t-online.de/downloads/hddreport.lha

Check icon information of HDToolbox. There should be a tooltype reading SCSI_DEVICE_NAME=gvpscsi.device.
Or "omniscsi.device", if equipped with a guru-rom.

Thanks guys a lot!.I managed to format the hard disk.Now the only problem I have is the LED of hard disk that does not work.

The LED on the hard disk or the LED on the front of the case? Did you confirm that the lead is plugged in correctly into the card?
-
The LED on the front of the case.The cables are plugged correctly but nothing.The hard disk(Quantum) has a light itself that work fine.

Try reversing the Power and HDD LED's briefly and see if there's any change. Assuming your front panel HDD LED is completely toast, there's plenty of replacements on ebay, looks like they're going for around $30 bucks right now. Alternatively, if you have the time and skill it might be cheaper to just repair your existing one.

Wow! What a rip-off! $30 for a 0.30$ LED. That's a plain standard rectangular LED, absolutely nothing special about it.
Problem typically is: Reversed polarity (unlike what people believe, it does not enable time travel or access to another dimension) or simply plugged onto the wrong pins. In worst case, some HDs have LED-out pins as well where you can connect it to (e.g. my old IBM did).
-
I ha tried reversing the power and hd led and the hdd led worked.I think the GVP card has the problem because the two LEDs work fine.
-
Some hard disks have led jumper.

30 bucks for led wtf lol
I bought 5 for free

To be fair the $30 bucks was for the entire front panel "module" (both LED's, wiring, and the plastic housing). Go look it up, plenty of them on ebay. This would be a simpler "plug and play" replacement, if OP didn't have technical skill or time to replace a smaller component.
But TL;DR, it sounds like his problem is with the HC, not the LED. Maybe try measuring voltage across the pins to see if it's sending any activity signal at all?
