I noticed what looked like a VGA output on the DIO box so I connected a PC monitor to it. It now gives me a monitor output so I can see the operating system trying to boot. The original drive boots to a text screen displaying MontaVista Linux logo at the top and then scrolls through a couple of pages of text lines whizzing up the screen as various things are being loaded.
After a few seconds it stops on some HDD errors as follows:
had: dma_intr: status=0x51
hda: dma_intr: error=0x40
End_request: I/O error
EXT3-fs error
Clearly there is a problem with the HDD, connecting the monitor is a really good way of confirming that is the case.
Installing a new HDD has gone smoothly but as it's blank it won't boot.
I created the 3 CDs and the floppy using the image files you gave me, thanks for your help here Bill. Now I have the monitor connected, I can see why I have no joy with them. The floppy drive spins up twice as it should but the system reports 'Not a bootable disk!' when trying to boot from the floppy.
The floppy has all the files on it but clearly needs to be made into a boot disk. Does anyone know how to make this into a boot disk for the MontaVista Linux?
I imagine that the old HDD is partly booting and therefore if I can break out to a command prompt I may well be able to create the boot floppy from Linux command line. I have connected a keyboard and tried pressing a few different buttons but I'm not getting a command prompt although I know the keyboard is working as I can get ctrl F11 to display a different error screen.
Alternatively, does anyone know how I can create the boot FDD from a PC?
Also I notice the ftp site address for the Yamaha downloads is incorrect on the link from their website. The correct address is ftp://54.183.42.154 and the username and password are still both 'disklavier', I noticed this link on these forums a year or so ago, come on Yamaha update your website! The image files and the floppy disk files are on that FTP but no instruction on how to make the floppy disk bootable if your Disklavier is dead!
Ideally they or someone would publish a .img file for the floppy disk as this is an equivalent of an iso and should contain all the information contained on the floppy including the boot files.
I think this is the final step and then I should be up and running!
Thanks for your support everyone.
Merry Christmas!
