bootnow under centos 6.5

Postby zephyr98 » Tue Dec 31, 2013 7:23 am

trying to put up bootnow under centos. not clear on instructions. the drvmap.inf info says to map / to device to boot bios. in my case root is on /dev/sdf3 and its sata. under drvmap.inf i have 80=/dev/sdf3

when i try anything (bootnow /None, bootnow 2, all i get is an unable to open device.

works perfectly fine under xp/ vista etc. i have bootnow on the path, permissions 755, drvmap.inf located with bootnow.

two questions. 1= what is the 80 all about in devmap.inf. ie, where do i see a list of bios drive numbers. and 2, what do i need to do to get it to work

Are you running bootnow as the superuser?

Also, you need to have a line like this in the file drvmap.inf:
80=/dev/sdX

...where /dev/sdX is the Linux drive that BIBM sees as hd0. Usually that will be /dev/sda, so the line would read:
80=/dev/sda

If that line doesn't work, the file /boot/grub/device.map may help determine the correct drive. You can type 'cat /boot/grub/device.map' to see the contents of that file. You can also use the command 'fdisk -l' to list all partitions on all drives, and then identify which drive is hd0 in BIBM based on the partitions you know are on that drive.

using the drive from the mount of / was the answer. (is used 80=/dev/sdf). using grubs device map did not work for me since i use the swap feature and thus hd0=/dev/sda.
too bad bootnow does not use the same file name as the win version (bootnow.inf). also, it sould include a default inf with at most the dev line commented out (ie. #80=/dev/sda). maybe an extra line or two of comment in the file would help. ie. making '80' a magic label for hd does not work for poor heads like mine).
ex: #point this to the host boot device /dev/sda, /dev/sdb etc.
anyway. now it works. and works well. tks
