FreeBSD 7.2 bootable disk doesn't work

V

varnie

good day.

today i've downloaded FreeBSD 7.2 Release iso images and burnt 7.2-RELEASE-i386-dvd1.iso image with the command:
Code: 
# growisofs -dvd-compat -Z /dev/acd0 7.2-RELEASE-i386-dvd1.iso
but i'm unable to boot from it. what am i doing wrong?

ps: i have FreeBSD 7.0 iso image written in the same way on another dvd disk and it boots fine.

as for my DVD drive info, here it is:
Code: 
acd0: DVDR <NEC DVD RW ND-3550A/1.05> at ata4-master UDMA33
cd0: <_NEC DVD_RW ND-3550A 1.05> Removable CD-ROM SCSI-0 device 
acd0: DVDR <NEC DVD RW ND-3550A/1.05> at ata4-master UDMA33
please help me:( many thanks!
 
thanks for link, but this doesn't work for me:
booting from 7.2-RELEASE-i386-bootonly.iso burned into DVD-RW disk faced the same problem as above.

interesting that when i mount this disk i see only that "iso" image and that's all.
but if i mount my FreeBSD 7.0 boot DVD-RW disk (which boots pretty well as i stressed above), i see all files and folders which FreeBSD 7.0 disk1 image contains.
 
good news, i've solved my problem.
as ale mentioned above, i've been burning iso image as file but not as an image. now i performed
Code: 
growisofs -dvd-compat -Z /dev/cd0=7.2-RELEASE-i386-dvd1.iso
and now i am able to boot from this DVD-disk. hurrah!
a few moments which caused a big pain:
*in order to perform burning i've had to
Code: 
kldload atapicam
module. the problem is that i've HAD to wait about 5 minutes seeing many errors in console until /dev/cd0 appeared as new device.
my console log on that moment:

* an interesting fact that in spite of that this disc now is burnt correctly, my XFCE4 && HAL doesn't auto-mount it when it is inserted. but as for my good old FreeBSD 7.0 bootable disk it recognizes by XFCE4 && HAL and auto-mounts without problems.

could you please help me? thanks!
 
1 step: kldload atapicam
2 step: insert not empty dvd disk in dvd-rom
and as result, catched all these warnings/errors in console
