Quick upgrade from Turbonet to Cachecard & vice versa

[wonderboy]

Hi There,

I have one main Tivo with Turbonet and a 'spare' tivo with cachecard, both networked.
Now what I want to do is switch the network cards, because I don't really use the spare one for anything useful, so I have a few Questions...

1. Can I install the driver for the Cachecard via network without pulling drive out and using the bootdisk? If so, how? (I would like a quick poweroff, swap NIC and power-on - no messing about)

2. Ditto can I stop the cachecard driver loading on the spare Tivo and swap out the cachecard with the Turbonet again without pulling the HDD?


Many thanks!:)

Yes - just follow the instructions for a Native Upgrade (http://www.silicondust.com/forum/viewtopic.php?t=340) from SiliconDust.

Thanks, will do that.

BTW, from what I can find the Turbonet is just a 10Mb card, with the cachecard being 10/100 - is this correct or are both the same speed?

Technically correct, but the limiting factor is really the speed of the Tivo processor, not of the network card.

With some tweaking you might be able to get 2.5Mbits out of it, but probably not much more, so the rated network speed is pretty much immaterial.

That's exactly what my testing has confirmed, copying files between the boxes is extremely slow, I was hoping that two cachecards may improve things but it sounds highly unlikely. Thanks.

I'm sure you mean 2.5MBytes ! 2.5Mbits is only 250k/sec ...:D

Anyway, yes a cachecard only gets you an extra 25% data transfer speed over turbonet (1.6Mbytes/s vs 1.9ish)

Thats 1900kbytes per sec tops...

Yep, you got me there! I always think of networks speeds in bits and wrote it down without really thinking about the values. I suppose I should have written down 20 Mbits...

And I am assuming that by "250k/sec" you mean "250kB/sec" and not "250kb/sec", which as you have pointed out is very different? :)

That comment got me thinking...if the Turbonet card is only 10Base-T, which is 10Mbit/sec, that means at most a transfer of 1.25 MB/sec.

So how where people getting 1.6MB/s out of it?

Or have I got my units wrong somewhere??

TIA!
