Ah, it is the classic problem, isn't it? There's hope though. Maybe your system is ipmi enabled. Ipmi stands for intelligent platform management interface. It's a way to control the BIOS/EUFI via the command line. If your system is ipmi enabled, you should be able to configure it to boot from a CD or USB stick. I would recommend you google it but here is a link on how to install ipmitool on Debian: https://linuxhint.com/ipmi-linux-command/ And here is a link to the ipmitool man page: https://linux.die.net/man/1/ipmitool On 3/14/23 16:02, Steve Matzura wrote:
I have no possibility of accessing the BIOS on one of my machines--no screen (the system is hopelessly buried behind other equipment) and no one to read it even if I had one. This system booted from its DVD drive at one time, but now no longer does, and I don't know why. I can mount the DVD with the command:
mount -t 9660 -o ro cdrom
and show the filesystem with df, but if I reboot the system with the reboot command or turn it on from cold, seems like the DVD drive gets bypassed. I have also tried booting the system from a USB thumb drive suitably prepaired with Debian 11.6 by writing it with IMGBurn, and still no joy no matter which USB port I choose. Is there a way to force the CD/DVD drive to boot from maybe an installed boot manager package that I can install on my Debian 8 system so as to boot the Debian 11 DVD and regenerate my system?
