Re: Sam460Ex AOS Display/Boot Problem

I've ordered a "super quiet" CPU fan and will see how that goes. It's certainly odd that mine seems to need so much active cooling though (I have emailed ACube to query this). Anyway, to prove it exists and runs now: https://lh5.googleusercontent.com/-HGKWwkm9EM4/VG3j3Z7D3iI/AAAAAAAADDo/dF...

Re: Sam460Ex AOS Display/Boot Problem

Possibly yes. I just installed a CPU fan (which sounds like a tornado so isn't a practical option for me as I like quiet systems), and it's run solidly now for 20 minutes, so it's definitely an overheating issue.

Re: Sam460Ex AOS Display/Boot Problem

Pretty much proved this now. Through being very patient (i.e. enduring hangs/reboots/waiting for it to cool cycles) I managed to install the 1.2 Radeon driver, and now have the correct full 2560x1440 resolution, which is nice. However, after a couple of minutes Workbench will either freeze solid, or...

Re: Sam460Ex AOS Display/Boot Problem

I think it might be a heat problem. More times than can be coincidence now I've left the machine off for a while and it's booted up fine when I turn it on. It hangs in WB after a couple of minutes though and after that point always hangs in IPrefs on boot, unless I leave it off for a while. Strange,...

Re: Sam460Ex AOS Display/Boot Problem

I'm giving up for now guys and starting fresh when I have the FE CD in hand. I can't help worrying that there is a hardware problem here but I'll just have to wait to find out for sure. Thanks very much for your help. (LoadWB half works but not surprisingly very little works, including networking, b...

Re: Sam460Ex AOS Display/Boot Problem

Thanks, I can't think of a way to get that on my system though, bearing in mind I can't get to WB, only the shell.

Re: Sam460Ex AOS Display/Boot Problem

So, managed to get the BIOS output back to my DVI display, through the HD5450 card again. I renamed screenmode.prefs in ENVARC:Sys to screenmode.x. On rebooting it hangs in IPrefs. I boot again and see that it is still called screenmode.x and has been copied (as screenmode.x) to ENV:Sys (or perhaps ...

Re: Sam460Ex AOS Display/Boot Problem

I'm aware of the menu way of doing it - hard to do with a blank screen though :)

EDIT - perfect thanks, will do that. If/when I can, it hung starting up AmiStore and now won't boot at all (black screen).

Re: Sam460Ex AOS Display/Boot Problem

Ok so I've switched back to the HD card now and the version of RadeonHD.chip is 0.61. Clearly it does support the HD5450 to some degree at least. Other problem now is that nothing prior to AOS appears on my monitor as I'd previously set UBOOT to use the onboard graphics. Is there a way I can switch ...
