ROM flashing of an very old ROM version P-IV card

[Kristian95]

My P-IV card has a very old ROM version, P4info reports the following:

Ok here is the output from P4info:

Opened PicassoIV.resource 1.6 at $8000254

is the ROM able to be updated all the way to v 7.4 or is the ROM and chips on the card too old version??

I have no problems with the FliFi... but I figured it might be nice to have access to the early boot menu and also figured it might be good to upgrade the ROM just in case (due to bugs in earlier versions)... the question is whether it'll be possible with a ROM this old ??

[Kristian95]

can anyone help me out ??

[Kristian95]

ok, thanks will try it out!!

I just tried flashing the ROM with v 1.11. I got the same result as with v. 7.1 and 7.4.

After starting the flash program, it says:

Board #1 at $42000000

Then it hangs (even the mouse is frozen). It seems it hangs even before it starts flashing because I've had no problems after resetting the miggy when it hangs... oh well, I guess my P-IV is just too dated for newer ROM versions  :-?

I have an eFlash card in the machine... I might try removing it and give it all a go again.

I have tried flashing the various versions 4-5 times now and I have thus far gotten the same reaction, the first time I think I left it there for at least 30 seconds and it kept being frozen... hmmm drats.

[Kristian95]

btw, does the screen update while it flashes the ROM or does it just freeze and then suddently say "Done" or return to a prompt ??

[Kristian95]

ok, I just tried removing my eFlash card and then flash with 7.4... same result... almost at least, it still got stuck (and I waited for over 1 minute without it getting anywhere) but niw it said:

Board #1 at $40000000

instead of at $42000000

Strange... but oh well, seems some of the chips on my P-IV might be too old for flash upgrade ??

[Kristian95]

during the last attempt of updating (having removed the eFlash card) happened like this:

I boot the A4000 without start-up sequence
at the prompt I start the P4FlashUpdate program, and it writes the following on screen:

Board #1 at $40000000

The mouse freezes right after that and then I wait.... and wait.... and wait.... after over 1 minute where the mouse and keyboard didn't respond I reset the Amiga... and it actually responded to Ctrl + Amiga + Amiga on the keyboard, and booted... the card still works, it seems the flash process gets stuck before any actual flashing occurs...

[Kristian95]

yup, I think you're right... oh well, most importantly the card itself works

[Kristian95]

ah, that's probably the reason alas I don't have the original 3640 board that came with the computer so I won't be able to try it out
