1.* versus 2.* firmwares in 6650A drive -- what's the difference?

The 6650A drive has 1.* and 2.* series firmwares, I noticed, and on the Liggy & Dee’s firmware page for that drive, it says not to cross-flash the drive to the other series firmware.

I haven’t found anywhere where anybody says WHY this is – are they different controller chips? Massively different hardware inside? What’s the story? Why the different firmware series in the first place?

I said that the drive should not be crossflashed by using Binflash! 1.* firmwares are for master and 2.* firmwares for slave drives.

Yay, connection specific firmware. I thought so but wasn’t sure about with this drive, so I choose to not post it (Shame on me).

Wait… so my drive came with a 1.* firmware. I put it into my Thinkpad’s UltraBay slot… don’t know if that’s master or slave (I’m assuming slave, I’ll have to check). I flashed it with your 1.* firmware, and it works fine. Does that mean it’s being treated as a master?

… also, does this then mean there’s no difference between the 1.* and 2.* firmwares except whether the drive is in master or slave mode?

If it works this way, don’t change it! How your notebook internally handles drives may differ of course. BTW: What Thinkpad do you have exactly? I might get a new drive soon and I’m not sure if it will fit in my notebook.

Most 2.** firmwares are no official firmwares. They are just 1.** firmwares changed to slave by me. But there may also be differences between 1.XX and 2.XX firmwares.

Hi Liggy!

Mine’s 3 or 4 years old – it’s an A31, which they don’t make anymore.
Takes the larger-sized ultrabay devices (not the “ultrabay slim” devices).

There’s a discussion about this on http://www.thinkwiki.org - I had to take the 6650A and attach the ultrabay connector on my existing CD/DVD drive (just screwed right on), and then slice a piece of the faceplace off, since the A31 has a little jag in the ultrabay port that didn’t fit the purely rectangular faceplace of the 6650A. It was pretty easy (bought a nice new Dremel tool to do it), although I can’t say I’ve ever had to hack a chunk of plastic off a piece of computer hardware before to make it work. :slight_smile:

Here’s some links (I didn’t have to do any glueing, as some in these threads did):

Liggy – so, what kind of Thinkpad do you own?

  • Tim

It’s not actually my Thinkpad. It belongs to the company I work for. I need to have a look when I’m back at work. But I think it’s either T40 or R40 - don’t remember exactly. :o

My XPS Gen 2 came with firmware 102c and the burner is indeed connected to the scendary IDE channel and appears as device 0 (master). Funny thing is, the only firmware available on support.dell.com is 203d (there’s no reference “older” verions as there occasionally is). Why would Dell do something like that? Won’t everyone who downloads and installs this firmware be screwed, if the premise of this thread true?

Please advice on how I should proceed.

Sorry, I take all that back. Although this firmware was listed under XPS Gen 2, it was really for the 6500 and, since it was the only NEC firmware, I stupidly assumed it was for the 6650.

I’d still like to hear what the recommended 1.xx firmware is. This burner is painfully slow with the stock firmware.

It´s thoroughly discussed here
