MikroTik

I had a working licensed router. I did a reset command to clear configuration so I could load a backup from another router. After doing the reset, when it rebooted, The following message appeared and then it hung and would finish booting.
Message "LILO - Keystroke read/checksum error".
Any information as to what is wrond and what to do will be appreciated.

The line should have said 'would not finnish booting'.

Why not try reinstalling routerOS and then restore backup, It sure solves this problem,I have tried it a couple of time and it worked

Do you install mt on IDE flash disk?

If You install on flash disk try to set in motherboard setup PIO1 mode for flash disk. We had exactly the same problem with PQI 64MB Disk-On-Module which in default use PIO2 mode.
