Obtaining firmware - can one use Sidux files?



Hello

Given the on-going problems described here before about my SATA CDROM drive, I ran Sidux LiveCD and then installed it onto my HDD over the weekend. My CDROM drive was picked up perfectly. Sidux was running the 2.6.30* kernel, so thinking that that kernel might have better support for the CDROM in question, I compiled a 2.6.30 kernel and safe-upgraded my system to sid from testing.

However, same problem persists.  This time though I can safely say that:

(i) the drive does not appear to be faulty in anyway (it was fine with Sidux right "out of the box") (ii) it doesn't appear to be due to the kernel version (having just changed from 2.6.26 to 2.6.30)
(iii) it doesn't appear restricted to testing/ "Squeeze" only

However, it may yet be:

(i) something to do with the SCSI controller it is using scsi1 and how could I tell? (I really don't think that this is the issue, but for the sake of thoroughness). (ii) one or other hitherto unknown module is not being loaded into the kernel. However, using hardinfo the CDROM drive is listed under storage, and both sr_mod and cdrom are listed as modules in the section under "kernel modules", so I am leaning away from the notion that modules aren't being loaded. (iii) it has something to do with firmware (I noticed that Sidux is pretty up-to-date with its firmware, and seems to have it listed as a repository)

So, my questions?

(i) how could I definitely test whether the correct modules are being loaded at boot time? (ii) how do I go about installing updated firmware for the CDROM drive? It is a TSSTcorp CDDVDW TS-H653Z drive from Seagate, revision 4403. Can I extract it from the Sidux installation/LiveCD and if so, how would I do that, what am I looking for?

I'd appreciate any further suggestions - thanks.

AG
