My preparation to 10.5.6 was unsuccessful. I have an AMD PC with Zephyroth Leopard 10.5.2 (initial) and GUID boot loader from same installation disk. Over time I've updated PC successfully with updates patched by bhast2 to 10.5.5 (Kernel 10.5.4) It is a perfectly working system. Today I've tried to prepare PC for 10.5.6 installation using biird way (comment 22) and it resulted in booting problem:

boot0: GPT
boot0: HFS+
boot0: booting
boot0: done
HFS+ partition error

No booting. Differently from biird I didn't have woodoo kernel. Is it necessary? Surely I've missed the development of OSx86 regarding new ways of booting. Is there resources for problem like mine? Or maybe there will be patched version of 10.5.6 or won't be anymore patched updates?

P.S. I'm doing initial updates to a testing version of Leo on different partition which is however is on the same disk as my working Leo.
