this is the spec I'm working on:

CPU: AMD Athlon 64 2800 + (SSE, SSE2, x86-64)
Memory: 1 Gigabyte
Chipset: nfroce3 250
graphics: ATI Radeon 9550 AGPx8
sound: ALC850
LAN: Marvell Yukon 88E8001

HD to install on : 80GB IDE, single harddrive.
installing from SATA DVD with Kalyway 10.5.2.

I've started working on it here: http://www.insanelymac.com/forum/ind...owtopic=187976
and got stuck in the middle.

I've been able to install the system once, and it failed after installing some kexts, so I've tried again and I can't bypass the first restart which result every time with kernel panic.

The settings I've tried:
default + JAS_SSE2 patch = kernel panic
test patch 1 + boot flag + JAS SSE2 no WIFI drivers = kernel panic (something with nforce)
default + test patch 1 + boot flag = ACPI kernel panic
JAS SSE2 + test 2 + boot flag = onboard pcata kernel panic
JAS + Nfroce mobo driver only + test1 patch + boot flag = kernel panic

Tried also iDeneb v10.6 Lite 10.5.8 and got kernel panic on boot before the installation.

any help or tip will be useful. I know it's a bit old system, but I've seen that similar mobos have been to work. I've also got a working Leopard 10.5.8 on vmware in a notebook, so if there is need to use leopard for something I can use it.

did you try "-v -x"? I found Leo4All AMD only kernel really good with AMD machines.

You need to get the latest version of the os. iATKOS v7...it has heaps more options for your cpu. Once you have aquired a copy and burned the iso to a bootable disk, go into the 'customise' propperties and select the 'kernel' designed for amd chips. Thats about it.
