====== Booting Ubuntu with BKO ====== ===== Locating from where does the nfsboot is getting called ===== ==== Mistory of do_nfsmount ==== //do_nfsmount// is defined at two places, why?\\ - ///scripts/casper +198// - ///scripts/nfs +8// My guess is that file ///scripts/nfs// is not used, it is just present there from older versions and has not been removed.\\ //do_nfsmount// function is getting called from ///scripts/casper +188// which is from inside of <code>do_netmount()</code> and depend on variable <code>${NETBOOT}</code> The //do_netmount()// is getting called from //mountroot()// which is inside ///scripts/casper +581// and the call depends on variable presense of variable //${NETBOOT}// which is the boot parameter value of parameter //netboot// ===== qemu + ubuntu 9.04 Desktop i386 booting problem ===== ubuntu-9.04-desktop-i386.iso is refusing to boot over qemu. I am using command line <code> qemu -cdrom /var/www/ubuntu-9.04-desktop-i386.iso -net nic -net user </code> It gives error gives error : <code> [ 3.284007] ..MP-BIOS bug: 8254 timer not connected to IO-APIC </code> and freezes.\\ I am using following version of qemu <code> $ qemu QEMU PC emulator version 0.10.0, Copyright (c) 2003-2008 Fabrice Bellard </code> The BIOS number was found and BIOS version used by qemu is as follows <code> QEMU BIOS - build: 08/15/08 $Revision: 1.209 $date: 2008/06/02 20:08:10$ </code> I had to update my qemu to version 0.10.5 then it started working <code> $ qemu QEMU PC emulator version 0.10.5, Copyright (c) 2003-2008 Fabrice Bellard </code> I am getting following errors in the process of booting. My guess is, most of these errors are related to failure of httpfs in providing requested logical block, but I need to confirm this. <code> Buffer I/O error on device loop0, logical block 272374 SQUASHFS error: sb_bread is failed reading block 0x845d5 SQUASHFS error: unable to read fragment cache block [211696cb] SQUASHFS error: unable to read page, block 211696cb, size c115 </code>
