I've also tried to get Zephyroth 10.5.2 to work, but got some weird errors after the successful installation.
After the first restart I was happy to see, that apparently everything was alright, so I could boot up via MBR...

After the spinner rotated for a while i got the "Restart your computer"-error, which is displayed in four languages. The same happened for me, as I tried to boot up using the "-x" bootflag

Next I tried the "-f" bootflag which caused a weird error:
EFI enhanced bootloader build: ToH
Using SMBIOS table found at 0x000fbdb0
Using ACPI RSDP revision 0 found at 0x000fa7c0

Before I decided to post it on this forum, I searched on the web and had a look on the wiki, but I couldn't find any solutions.

Does anybody have an idea or a hint for me, what could have caused these errors?

Author Update #1 @anna 2008-02-29

ok thanks for your answer, i'll try this after work tonight. if it solves the problem, we may add it to the "known issues" on the wiki.

Author Update #2 @anna 2008-03-05

Ok, after I turned off any power management options, the error disappeared. Thanks for that so far…

But when I try to boot up, I still get the "Restart your computer"-error, I also reported that on my first post.

So I tried to boot up with displaying diagnostic messages ("-v"). But everytime the boot process stops at a different point. The log doesn't go on, and I cannot hear any noise from my HD (which is usually that loud, that I can hear it working)

I also tried to repair the partition permissions etc., using the dvd. Any help?

Field Note #1 @art 2008-02-29

I have such problem - turn off ACPI 2.0 at bios (like all advanced power management options) and it works.

My hardware is 3200+ @ KT800Pro chipset

Field Note #2 @art 2008-03-06

Try turn on only one core and use -v -x.

P.S ? ?-? ? ?, ?...

Field Note #3 @man_of_the_oak 2008-11-23

I have asus p5vd2-x motherboard. I have found an option to turn off acpi support but it's gray, so that I can't disable it. I've read somewhere over the net that it's due to Core 2 Duo E6300 processor which I own. I've tried also booting with "platform=X86PC", "acpi=off", "-v -x cpus=1" etc. but I couldn get it work. I've also tried just waiting about 1h in hope of getting it work... ofcourse it didn't help to. Can anybody help me? I am desperated :'(

p.s. tried with leo4all 10.5.2 and Kalyway 10.5.1
