this is what came back from terminal: 54 0 0xffffff7f839fb000 0x4000 0x4000 as.lvs1974.RTCMemoryFixup (1.0.3) 2107893D-2CCA-30EF-A637-18A23310C289 <36 7 5 4 3 2 1>

I take it that means its loaded? - Will find out from cold boot in the morning if its fixed. Did a start a couple of times without issues so fingers crossed.....Appreciate your assistance Justin
 
yes, that means it is loaded. why don't you shutdown your machine and turn it on again to verify. I am not sure if this kext could fix the problem you had, i never had that issue, though.
 
ive done that - it didn't happen but its usually first thing after a cold start and sometimes later too so as its not every time ill have to just see over a couple of days. doesn't seem to have the done the build any harm though......ill let you know
 
ok - had a few days off from boot failure so I thought that had sorted it - but today from cold boot I got one so its still happening :(
 
You could always use the MultiBeast10.4 RTC option and remove the kext you downloaded (and rebuild caches after). Worth checking because it does indeed sound like RTC.

Can you send me your DSDT.aml? or let me your current BIOS version.

Here you go - BIOS is the last proper version for the board (F7). and thank you!....

Hi Utter! - how do you rebuild the cache?

try remove the rtcmemoryfixup.kext and the boot arg, check another 2 options:
