There are only CD ISO image in the FreeBSD official website. installation FreeBSD by 2 or 3 CD is inconvenient. we need replace CD one by one. so a DVD installation disc will save a lot of times and work.
The following Tools will be used in the work of creating DVD ISO image: WinRAR, CD ISO 1 to 3 of Freebsd(I use Freebsd6.3), UltraISO (winISO also can work in this project, but I like UltraISO) and emeditor(or any editor who support unix text format). Moreover if you want burn DVD-ROM, your need software of burning and DVD-RW driver and DVD-R or DVD-RW disc.
