Sain pienen säätämisen jälkeen Ubuntu studion asennettua koneelle. Toimi hyvin viikon pari, mutta tänään käynnistäessä ilmoittaa että:
error 18: selected cylinder exceeds maximum supported by bios
Kumpaakaan, biosia tai levyosiointia ei ole muutettu mitenkään. Lakkasi vain yhtäkkiä toimimasta.
Emolevy on Asus A7N8x, biosin versiota en löytänyt, Phoenix AwardBIOS on nimeltään. Kovalevy on Samsungin 80gb levy, joka on osioitu ubuntustudion asennuksen yhteydessä oletusasetuksilla.
Löysin jo ohjeet korjaamiseenkin, mutta nämä ovat vähän liian yleisluontoiset minun kyvyilleni, siis jos joku osaa selittää niin että vähän huonommin tekniikkaakin ymmärtävä tajuaa, niin olisin hyvin kiitollinen:

Error 18: Selected cylinder exceeds maximum supported by BIOS
This error is returned when a read is attempted at a linear block address beyond the end of the BIOS translated area. This generally happens if your disk is larger than the BIOS can handle (512MB for (E)IDE disks on older machines or larger than 8GB on others.). In more practical terms this means the BIOS is unable to start executing the kernel because the kernel is not located within the block it can access at boot up time.
This can be circumvented by creating a boot partition at the beginning of the disk that is completely within the first 1023 cylinders of the harddrive. This partition will contain the kernel.
The kernel itself does not suffer from the same limitations as the BIOS so after the BIOS has loaded the kernel the kernel will have no problem accessing the whole harddrive. Newer BIOSes will automatically translate the harddrives size in a way that it can be completely contained within the first 1023 cylinders and hence modern computers do not suffer from this problem.
The same error can happen when the BIOS detects a disk in a different way as Linux does. This can happen when changing motherboards or when moving a GRUB-bootable disk from one computer to another. If this happens, just boot with a GRUB floppy, read the C/H/S numbers from the existing partition table and manually edit the BIOS numbers to match. If using a SUSE linux and installing on VM Ware this problem is solved by creating a small partition at the very beginning of the harddisc, and mounting it as /boot.
