info good info for upgrading tivo

Nice to have all these in one place.

Mount (make available) your CD-ROM

#mount /dev/hda -t iso9660 -r /cdrom

After the cdrom is mounted you can check with the disk free command (df) that it is correctly mounted at the /cdrom directory:

# df

Unmounting your CD-ROM

#umount /cdrom

or alternatively you can type

#umount /dev/hdc

Be sure to turn DMA on for both drives:

# hdparm -d1 /dev/hdc
# hdparm -d1 /dev/hdd

(where X and Y are the correct drive letters). Makes a HUGE difference (25 hours for a 120 gig dd verses 2 hours for the same setup). To see the speed difference do a:

# hdparm -t /dev/hdX before and after during on DMA.

# mfsrestore -s 127 -xzpi /mnt/dos/tivo.bak /dev/hdc (restore/expand to single new larger A drive)
# mfsrestore -s 127 -xzpi /mnt/dos/tivo.bak /dev/hdc /dev/hdb (restore/expand to new A and new B)

Finally you can unmount your drives using the following command:

# umount -f -a -r (umount not unmount)

When finished, press Ctrl-Alt-Del and wait for the 'No more processes ... ' or it reboots then power down.

# fdisk -l (that's l as in list) as root. That command will simply list your disk partitions and exit.

# tpip -p /dev/hdX List partition information

# mfsrestore -s 400 -r4 -zxpi /mnt/backup.bak /dev/hdd
# tpip --swapped -s /dev/hdd

At # prompt both Boot Cd and Floppy users type the following commands to mount your C: drive:

# mkdir /mnt/dos
# mount /dev/hdb5 /mnt/dos
