relikwie Posted October 15, 2009 Share Posted October 15, 2009 I have the same CMOS checksum error when trying to install snow leopard. Using the SLboot method, installartion of SL restarts unexpectedly and I get the CMOS error (loading defaults). I think it has to do with chameleon RC3 Link to comment https://www.insanelymac.com/forum/topic/192048-cmos-checksum-error-restart-failed/#findComment-1299274 Share on other sites More sharing options...

I think it has to do with chameleon RC3 hi, no chameleon is not the reason there's much more todo, follow this post after that • name your dsdt.aml always to DSDT.aml • put it into /Extra • edit your com.apple.bool.plist add following: <key>Wait</key> <string>y</string> boot with "-v" (verbose mode) you will get some output and a "press any key bla bla bla" message look above this line, chameleon should tell you if a patched acpi table was found, if not, your dsdt wasn't loaded.

relikwie Posted October 15, 2009 Share Posted October 15, 2009 bert, correct. just figured out and wanted to help yehia out. RTC should be fixed to get rid of the CMOS reset.. Chameleon.. you're the best giving the opportunity to load a custom DSDT.

Chameleon.. you're the best giving the opportunity to load a custom DSDT. yes, but sometimes only changing the rtc in dsdt would not work because of the IRQ entries, that's why i posted the link to the hpet, rtc, pic, tmr, etc. fix Link to comment https://www.insanelymac.com/forum/topic/192048-cmos-checksum-error-restart-failed/#findComment-1299687 Share on other sites More sharing options...

relikwie Posted October 21, 2009 Share Posted October 21, 2009 thanks.. had patched dsdt etc, cmos was gone, but still the pc would restart after 15 minutes or so.. so partitioned first, rebooted, then went trough the installation very quick unchecking most options and withing 15 minutes the installation was done and I could restart via the button. everything runs smooth now.
