"...The LinuxBIOS gunzip's the Linux kernel straight out of NVRAM and essentially requires no moving parts other than the fan. It does a minimal amount of hardware initialization before jumping to the kernel start and lets Linux do the rest. As a result, it is much faster (current record 3 seconds), which has sparked interest in the consumer electronics community as well. Moreover, updates can be performed over the network..."

Not for the faint of heart, or those lacking the approriate hardware (i.e. EEPROM burner).

hi all,

i am using a laptop, so i reboot very frequently. i have been tried to make the booting process faster for a long time. right now, i had done following reduction on my system:

1) NO X at all (use emacs and links in framebuffer).
2) no modules at all, everything in kernel.
3) no network, cron.

with these reductions i lower the booting time to 19s with kernel 2.4.22. however, with kernel 2.6.1 now it took more than 25s to boot, partially due to hotplug and alsa.

is there anything i can do to make it even faster? 10s will be my goal. thanks for any idea!
