0FL01 error

[Ketxxx]

On it, heres what I think is the right pin layout as the chip appears to be SOIC and not SAP, config look right to you?

http://www.atmel.com/dyn/resources/prod_documents/AT25F512A.pdf that may shed more light for anyone wanting to read it.

THIS would also suggest that the AT25F512 is a 256k ROM chip.

Ket ... so are you going to use the WP and VCC pins to do low and high voltage present?

 

[Ketxxx]

Probably. Just a lot of hassle. May just cut the leg for WP to start with to see if I get lucky.

 

[Urlyin]

flash and solder back?

 

[Ketxxx]

Hell no, once the WP is disabled (hopefully just by cutting leg 3), its staying that way

 

[Urlyin]

lol .. that is if it works ... good luck

 

[Ketxxx]

Better do. My Ket sences are tingling saying this card is hiding something.

 

[Ketxxx]

Right, I'm sure this is enough voltage but best to be sure I got a reading of 3.1v going through the ROM chip, I know its operational voltages are between 2.7 - 3.6v, So the chip voltage is good I assume. Just mainly curious about if that gives me anymore solid evidence to suggest cutting the WP leg will disable write protection as I read somewhere that this ROM chip isnt writable if its voltage is below 2.8v or something.

Can anyone verify this for me before I go buy new vmod stuff?

When I had my HSF off I looked for 570 and couldn't find it either and mines a Sapphire >_> I don't recall seeing RV either.

 

[Ketxxx]

Right, I'm officially pissed off. farkin ROM chip is still insistent its write protected

 

[Formula350]

Well thats the same error I had gotten remember, and you just said -f it lol Which worked.

 

[Urlyin]

no go Ket? Did you try the jumper wire ..

 

[Ketxxx]

Yea. maybe I'm missing something I dunno. First time I've had to mess with a ROM chip. I still dont get why this farking card had to have its ROM chip locked. Just seems odd when my last POS 1950Pro wasnt. Dont spose theres anyone who lives near me whos messed with ROM chips who wants to come and give it a bash? Dont think I dare running the risk again as I used a 85-110w (or something like that) soldering iron

 

[Formula350]

Try this maybe? http://www.uniflash.org/history.htm

fixed Flash ROM write protect enable/disable

And this is dealing with a Motherboard, but might provide some help.

[Ketxxx]

i found that uniflash too, but was under the impression it was for mainboards only?

 

[Formula350]

Yea, you're right, and the chip you have isn't supported either.

Another long shot :\ http://www.cbmhardware.de/cbmpet/romram.php

 

[Ketxxx]

downloaded it, but thers only a .prg file in the zip found that mobo link too, sadly no help. Only thing I can think if is maybe my type of ROM chip isnt currently supported?

 

[Formula350]

Needs to be ran in BASIC? I dunno about programing at all :S

Flash Programmer for CBM Basic 4.0

 

[Ketxxx]

I dont have that.. fek.

 

[Formula350]

OK Can you SAVE your BIOS? If so, can you write your newly saved stock BIOS to the card? Just to test? If so, maybe it's being an ass about SSID? If you know the BIOS you have's SSID, I saw that in the flasher programs you can change your cards SSID . . It's like -rd and -md

 

[Ketxxx]

I already tried that, I can get a dump of my BIOS without issue. It wont even write the dump I dragged from the chip tho. So deffinately a locked ROM chip, or I should say, what appears to deffinately be a locked rom chip.

 

[Formula350]

Does the manufact have an updated BIOS on their site? If so, then you can call them and ask WTF w/o worry. I guess you COULD call but saying "I'm trying to flash my bios and am having problems" when they don't offer one, might not go so well lol

 

[Ketxxx]

They dont have an updated BIOS, and the drivers on their site dont even support the 1950Pro.. tho I guess I could try contacting them, stating I'm having a DVI issue, ATI themselves gave me a BIOS that addresses the issue, but now I'm finding I cant flash the updated BIOS. Maybe they will cough up a special flash program. After all the ROM chip has been programmed, so there must be some tech software thats used to flash the chip in the first place as I doubt a card would be produced with its ROM locked, soldered to the PCB, then unlocked only to be flashed and locked again.

 

[Formula350]

Ah... yes... I think that might work! Get on the horn!
