Hi to all! So after gathering many info i tried to install iATKOs v7 on my Toshiba satellite L40:
Intel dualCore T
Hd Toshiba SATA
chipset Intel GML GL960
Video GMX3100
Audio ALC660
Wired Network Realtek 8139
Wireless Network Realtek 8187B

I created a partition in Windows vista of about 22Gb in RAW.

After starting from iATKOS DVD i went to Utilityes --> DiskManagment and select the partition just created, choose Mac OS X Extended (Journaled) and click Erase.

Than back to menu And in customize i add the option:

Kernel 9.7.0 Vodoo
Intel SATA/IDE
APIC x86
dSDT patch
Laptop Battery
decrypt appledecrypt
Vga Intel GMAX3100
Network Realtek 8139
Network Realtek 8187B USB

And install
On reboot i had:

Boot0: testing
Boot0: testing
Boot0: testing
Boot0: error

And pc stop here
So i use Windows vista DVD to' repair and than after reboot start only vista directly.

Than i start over using iPC 10.5.6 Final PP5 DVD, same customize option, maybe with PS2/driver for keyboard.
*After installing, at reboot it gave me this:

Please contact the Vodoo kernel dev-team....... (And other things)
panic (cpu 0 caller 0x00.....): kernel trap at 0x00....

And a page of number

Debugger called <panic>
Backtrace (CPU0) Frame: return address 4 potential arg
And Than numbers

And below

No mapping exist for frame pointer
Backtrace terminated-invalid frame pointer 0xb....,

So i forcely reboot and start vista, download easyBoot and try something but the result is that at booting i have Windows boot manager and *the choice of.. Windows Vista only

So i start over with iATKOS v7 and same option and same panic screen.

But when i reboot i see for while, before Windows boot manager screen:

Booot ..something
Boot.. something

But i cant see it very well, im not sure, its too fast

Anyone please can Help me?

I solved: after trying many installation from iatkos and iPC, with error Boot:0, i tried using fdisk, diskutil diskpart.. Only error or boot0: mbr boot0: done boot1:error.
The real Problem was that in creatina the partition for Leopard from disk manager of vista, the partition was Logical! I used easus partition software and delete and ricreate the partition Primary and the install went ok! After reboot OsX started without DVD!
