cringemaster Posted December 28, 2006 Share Posted December 28, 2006 Hmm, did you update the firmware? I know that is always a problem causer among old imacs.

OMX-Knuckles Posted December 29, 2006 Share Posted December 29, 2006 You'll need to wipe the hard drive and install 9.0.4 or 9.1, update the firmware, and install 10.2 again. We had a similar issue with an iMac at a place I used to work. After 10.2 was installed the screen was hosed until I put 9.1 back on and updated the firmware. The firmware update MUST be done from 9.x, not X or Classic inside of X.

toddicus Posted December 29, 2006 Share Posted December 29, 2006 They're both right, it's a firmware update problem (most likely) some people actually cooked their video cards in the old iMacs. You should be fine with the firmware update, I believe it's on the OS X install CD, not 100% sure of that though. Check the 10.2 install CD I think that's where I found it and recovered my iMacs.

McSkywalker Posted December 29, 2006 Share Posted December 29, 2006 Get the update from here and read the guide carefully. Make sure not to skip the programmer's button thing.

OMX-Knuckles Posted December 30, 2006 Share Posted December 30, 2006 On a sidenote, does anyone know why firmware updates are so often required on Macs when upgrading the OS? I've been dealing with them since 7.5.1 on my 6360 and I'm sure they've been needed for long before that. It just seems odd that such odd things can happen. I've never run into an issue quite like this on PC's; occasionally an older PC will have issues with booting a new version of Windows and ACPI problems are quite common on pre-1999 machines. Just seems odd to me that your display would get garbled if you're not running the right firmware with a certain OS. Huh?

Making a firmware that is quite optimized to a specific OS makes it work a bit better. It's a trade off, slightly more updating when upgrading, and slightly improved system performance.

I'm pretty sure it's compatible. The last OS X to be officially supported on that machine, 10.3 required built-in firewire. You cleared the programer's switch thing right? resetting the PRAM never hurt anything, other than that I don't know what might be going on.

McSkywalker Posted December 30, 2006 Share Posted December 30, 2006 I can confirm that all of the Mac OS releases work on iMac Rev A. I did it myself. It's true that the 10.3 is the latest officially supported Mac OS X, but I was also able to install Tiger with the help of XPostFacto. I replaced the original HD cable with a regular PC HD cable. I hooked up my HD as master and my Toshiba DVD drive as slave, setup XPostFacto from OS 9 to startup from Tiger DVD and to use the HD as helper disk. It was pertty easy to install and even on Tiger I didn't encounter any problems like you're talking about. Nevertheless, it is obviously too slow. Maybe your battery is about to die. The machine is old enough for it. Does the machine have problems with date and time? Does it reset back to something like 1956 or so?

Thanks McSky i have to download the OSX 10.3 version o 3 CD from Torrent and install. And runs with a 8 of Xbench score I change the memory of sides, 128+32 to 32+128 and work better, may be the buttom of the little board need more memory, i think. Then the weird off dissapear. i Try to install Tiger but not recognize my DVD drive with a Standard IDE cable, or may be need to follow the XPostFacto's instructions.
