Boot image ?

[nimzov]

I just downloaded freebsd 7.2.

I now would like make a bootable DVD for the installation process.

My problem is with the "boot image". Where do I find this
boot image ? Is this a generic or a freebsd file ?

I know there are a set of boot disk like:

boot.flp
kern1.flp
kern2.flp
kern3.flp
etc...

But I do not understand if a boot image is a generic file related to
my computer (used for any bootable dvd) or is it a freebsd file related
to this particular installation ?

I use ImageBurn (on windows 2000) and it ask me for the boot image and
I have no idea what file this is. Is boot.flp what they call the "boot image".

Thanks for any help on this matter.

Of couse I have googled but did not find anything.

Hello,

usually you don't need any special boot images. You simply burn the image of the DVD and then boot directly from that. The .flp files are meant to create boot floppy-disk's.

You probably got an .ISO file (or several .ISO's) that you burn on DVD (if they are meant for DVD, that is). Then simply insert the first DVD, tell your computer to boot from CD/DVD first (setting in the BIOS), thats it.

Also, check chapter 2.3.7 here (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/install-pre.html).

Hi thanks.

This was my first attempt.

1- Downloaded 7.2-RELEASE-i386-dvd1.iso.gz

2- Extracted 7.2-RELEASE-i386-dvd1.iso with winzip

3- Burn this ISO image to a DVD with no boot image with ImgBurn

4- Set the BIOS of my freebsd box to boot from the CD-ROM

Problem I have is that all the files are on the DVD but it won't boot from the DVD-ROM. So I thought I needed a boot image on the DVD.

I will make another copy and see what happens.

Ok this DVD will boot to the freebsd setup screen on another computer.

So the problem is most likely with the CDROM or the BIOS.

Yea, i have seen BIOS implementations that had trouble with booting from DVD, while CD worked just fine. But these were older machines.

Also, do you use a different DVD drive for reading than you use for writing? Not every DVD-ROM drive may be able to read every writable DVD media. There is DVD-W, DVD+W, DVD-RW, DVD+RW, DVD-RAM .... and all that in double layer too nowdays. In addition, there are several different types of each available, depending on what chemicals they use. So, one DVD-R may be fine to read in a given DVD-ROM drive, while another DVD-R may fail to be read.

Yes I write and read from two different drives.

First time I have to consider such compatibility issues.

Thanks
