40 sec here with 10.5.2

52 sec with 10.5.4

Since I moved my OSx86 10.5.3, 9.3, EFi V8 install to an internal IDE HD, boot time is 25-30 seconds.

Gigabyte 6100/430 s939 MB with Athlon 64 X2 4200+ dual core CPU
2GB PC6400 DDR2 dual channel RAM
8600GTS 256MB video card
PCI Realtek 8169 gigabit LAN card
onboard ALC880 audio

My Phenom install boots in 40-45 seconds - booting off a 60GB 4200RPM 2.5" laptop HD in a USB 2.0 enclosure:
Zephyroth 10.5.1, Chameleon EFI for Phenom, Zephyroth ASU 0.5 update to 10.5.3, 9.3 modbin kernel:

onboard RTL8111c LAN
onboard ALC889a audio

15 seconds here.

(10.5.4, kernel 9.4.0, FireWire kexts removed)

Which kexts exactly did you remove, and is that why your boot is so quick?

IOFireWireFamily.kext and IOFireWireSBP2.kext removed. I dont use any firewire ports so i removed them. It was fast booting even before, when i removed them i think it's a bit faster. Its absolutely accurate cause i used stopwatch on my cellphone, from vista bootloader when i pick Mac (hit enter) till desktop shows up.

@milanca, I have simply disabled Firewire in BIOS, because I currently have no need for it either.

Oh yes, simplier and smarter way. i did it longer way but never mind, its fine working.

a reset takes about 5 secs!!!! Ooops thats my Amiga lol. Seriously got to get to the reason I dont have quick start up times of either of the systems ive got OSX on
