Hello.
I understand one of the biggest merits of LinuxBIOS is fast booting.
Then, how fast it is? The top page of the Wiki says 3 sec, and "7/25/01: Dual Athlon update " issue says about 2 sec to boot a kernel. But this log shows it took 20 sec.
The dominant factors are device driver init/probing and starting services. Thus, boot time will be very dependent on system configuration. For the the 3 second example I booted to a shell prompt using an initrd image, serial console and not much else. Most real systems are going to take a fair bit longer than that.
The main difference w/linuxbios is that the kernel is loaded and running in under 1 second vs. 10-50 seconds for a COTS bios. How fast things go once the kernel is booted is up to you.
Cheers! Ty
FAQ entry anyone?
