I was given several PCs that have some type of embedded disk drive that contains a custom Linux Kernel that only runs one main program. I need to gain access to the disk to change the root password so I can gain access to the systems. I attempted to boot a Fedora Live CD and started the process. fdisk reveled three partitions. 1: Boot Partition (1.5MB) 2: OS Partition (238MB) 3: Main program space (6.5MB) I am able to mount partition 1 and 3 without any problems but partition 2 reports:
# mount /dev/sda2 /mnt/sda2
EXT2-fs (sda2): error: can’t find an ext2 filesystem on dev sda2
FAT: invalid media value (0x77)
mount: you must specify the filesystem type
I’ve tried several different types and none have worked. I know for sure this partition contains the critical files I need because I can not find any linux os files on the other two partitions and the lilo configuration file on the sda1 (/etc/lilo.conf) specifies /dev/sda2 as the root disk.
Just for the record I have no access to any utilities nor console when the system is booted. The only thing I can report is when use Ctrl+Alt+F2 to be presented with the login prompt it says the Computer Name is “SuperStation”. I would appreciate any suggestions.
See this post for how to use the program file to get format.
