Thanks to this great forum I had a lovely dell mini 9 running os x. Pretty fast too. I lost Blutooth functionality and unfortunately I made the strategic error or trying to reinstall dellefi. I got the grey screen with lines which i have previously managed to banish, then when i rebooted, the mini loads the dell logo, briefly displays chamaeleon logo then shows the apple logo (but the wrong one with a curved line across it and the wrong resolution - instead of the plain white logo on grey background) I then get the timer and then the screen goes blank, the power indicator goes off (even when plugged into the mains)and the machine is powered down.
I have spent most of the weekend trying to sort but my experience of this sort of thing is limited.
I get the error whether booting from 10.5.8 on the SSD
or from a freshly prepared netboot installer 10.5.1 on the SDHC card plugged in via a USB card reader (i havent tried OSX from a USB as I dont have an 8GB stick). I thought maybe I had messed the bios, but cant find a way to re flash it as it says it is already that version.
Anyway in doing that i proved i could boot into dos with a flash loader USB stick without power down issue. Also managed to see windows 98 boot screen from a usb stick though it didnt seem to finish loading.
I tried to do dell boot 123 from an external usb dvd drive, like i did with original install but can't get it to load - I always found it a fairly random affair.
I really miss my mini and its pretty much a paperweight. I did try plugging in an external monitor just before the power problem arose (to try to solve the grey screen with lines problem) but didn't manage to get a signal on it, but I can't see that this has caused the problem.
I have tried to get os x to boot into safe mode but despite following lots of threads on here I haven't managed to do it when booting from SSD
or SDHC flash.
I feel sure I must be doing something dumb and this is a beginners problem that has been covered before but I cant find a solution anywhere.Help wanted urgently
