TC 3.8.4

Something I've just realised, with all TC versions 'tested' till now, 'fd0' has been missing from the equation!
Code: [Select]
                                                                                                               MOUNT TOOL DISPLAY
                                                                                                                   ---------
From now on the 'mount tool' displays not just 'sda1',                                                            |  fd0    |
                                                                                                                   ---------
and the boot varies in behaviour depending on the CD!                                                             |  hdb    |
                                                                                                                   ---------
                                                                                                                  |  sda1  |
                                                                                                                   ---------

NB. Non-standard mount points in the following results are indicative of failure on the part of the 'mount tool' to mount the respective device.

2.  CD '7P' in CD ROM Drive (Burnt using Brassero under Mint) gives rise to a host of boot errors because the boot INsists On reading the CD in the drive, although it is perfectly capable of informing about the Jolliet Extensions without a CD to read. After an inordinately long time it gives up and normally completes the boot, with only one incident of the system freezing.

Maro, hopefully lots of useful data for you to get your teeth stuck into :)

Well, I'm not going to let the grass grow under my feet. It's gone over a month now, barring a holiday or two, and not a peep from the team. It's somewhat disappointing that the team have not seen fit to acknowledge my effort to provide a comprehensive set of results, nor bothered to supply any explanation for some of the puzzling facts I pointed out. :(

When 2.6.33 worked I could very well have gone off and not come back to you at all, and left you guessing. However I know from my stint in 1st Line and s/w support that we would be glad of any feedback for a fix, and we abhorred it when this was met with complete silence.

Hi Tejas
It is not reasonable to expect an operating system to function properly if you try to run it on faulty hardware.
Whether that dead drive is a source of your problems is unknown, since you won't take the time to learn how
to operate a screwdriver so you can disconnect it. Speaking for myself, until you remove this unknown from
the equation, I don't see any point in pursuing this any further.

Hi Rich

As far as I'm concerned 2.6.33 does the job, and there's no point in taking anything further!


P.S.  I'm dependent for all my printing needs on the parallel interface of the old box.  So should I take a screwdriver to it and short something of vital importance, I'll be  up for a new USB printer. :(

If you don't know how to unplug a computer, and remove the connectors from the faulty drive, maybe you should not be using it.

I'll use it until it gives up the ghost ;)

Well, as I said above, I had to disconnect the (dead) hard drive for my old computer to be useful any longer. Maybe that's more like amputation?
