I m looking for "guru rom" for my gvp a530..is anybody know where can I get it thanks

Can you explain a bit more about it?

Its a replacement ROM for GVP SCSI cards and the A2091, basically a driver update if I remember correctly.
Sometimes they use a different ROM and a little adaptor board is used. (sometimes=always?)
Anyhow its an upgrade, not something that comes with the card as standard.

It looks like softhut have the Guru rom for the A2091 and the GVP Z2 card, dunno if the Z2 one works in an A500 card though.

Seems the adaptor board is required, the only other site I found (after a two second google) was updates for people who already owned the Guru rom boards.
(It says on the website "These images are updates for legitimate owners of the original Guru ROM only, not an excuse for cheapskates to devalue these dealers' remaining stock." so I wont post the link to that site.

For more info on the Guru rom visit Amiga-hardware.com

you mean Ralph Babel's site. no harm in providing the link as I'm almost sure SoftHut don't have them in stock anymore, and there's no way to make use of the Rom Image without the adapter board, which contains a programmed GAL chip whose interior is unknown to even Ralph Babel himself.

It would take 5 mins to work it out if I had one.

Well, I have one, but I'd like another, and I can program GAL chips. What are your suggestions for working it out? If you do a google search, there was a discussion somewhere of theoretically what the GAL is doing, but I don't think anyone has ever attacked one with a logic analyzer.

Five minutes of booting and running on the logic analyser here at work.

I contributed to that discussion. We need one to try. I have a GVP HD8+ all I need is the adapter and I'll open source the results.

If Ralph doesnt mind.

If anyone knows where you can officially buy these chips + adapters that would be better than trying to "steal" other peoples hard earned work.

The problem is, such a place do not exist.

I appreciate Ralph's hard work, but without anyone making use of it ... it doesn't have much meaning.

Thank you for your order, sorry we can no longer get the Guru rom as they stopped making them.

If you need anything else please let us know.

Thank you

Hi,

   Sorry to bump an old thread, but have you heard anything more on this subject?  I can call Compuquick/MrHardware  tomorrow, but Eternity's doesn't seem to want to go to English and I'm afraid I never learned more than pigeon German.  The Italian site only lists for the A2091 not for the GVP card.  I have only the GVP SCSI hardcards.


Thanks,
