Yes, this is a good approach. You can place the Linux kernel on the BIOS and rootfs can still on the CDROM. I don't make tests but I think read from BIOS Flash (LPC = ~16.7 MB/s) is more faster than read from 48X CDROM (48 x 150KB/s = ~ 7MB/s) > So, combining your way and my way would be a right choice. > Yes, once we don't have BIOS flash more than 2MB then this combining is the right choice. > And, the problem is not only BIOS, but a firm ware of CD-ROM also. > In some drives, to recognize a medium and start reading requies more than 10 > sec. > I mean, to start reading uses more time than booting Linux itself. > To solve this, probably so-called "LinuxFirmware" would be necessary... > > I need ATAPI commands like these. > SET_MEDIA( media_type="CD-R", media_format="SINGLE_SESSION" ) > START_SPIN( speed="MAX", wait=0) > If you can send these commands in the early stage of BIOS booting, > it gets more faster to start reading a medium. > Hmm, so this is the trick to get Linux booting in 10s :-) You will get best results using LinuxBIOS. > --- Okajima, Jun.
