Is anyone using a laptop?

Just get a Mac you tight arse...

I can't afford a bloody Mac, much as I'd like one. No time to learn a new sequencer either.

Timo, that was excellent advice, thanks mate. I'll defo bear that in mind. Actually, my regular interface is an RME Multiface which has to use its own PCMCIA card on a lappy. For a cool €275

I've just got the opportunity to get my hands on a fairly decent Samsung for next to nothing. Dunno what I'll do with it though. Probably just use it for Power Point presentations at work..

How do you now which FW chipset is in a particular notebook computer? The sales guy sure as hell won't know

Yep, it's an absolute arse, and the sales guys certainly won't have a clue.

Several ways to find out.

1) Go to the laptop website and look at the software drivers download page, and see who the firewire- or express-card(sometimes still called 'cardbus')-controller chipset driver is made by. An example would be such as the Dell Vostro software download page [here]. For that example, click the chipset tree and you'll see Intel (the CPU chipset) and Ricoh (the firewire/express-card chipset) drivers.

2) If you have a test laptop available to look at, a very easy way to find out is to run a free system analyser program such as [Sisoft Sandra Lite] or [Everest Free] on the laptop itself and it will tell you. Takes about 15 seconds to analyse the system, and it will include the firewire/cardbus chipset info.

OR you can post on the [PC section] of the SoundOnSound forums to ask about various models. They're pretty on the ball regards the TI stuff.

OR you can get someone nice on any laptop forum sites (two good sites are www.NotebookForums.com and www.NotebookReview.com, but they are mainly gamers) to run one of the system analyser programs on their computers for you as a favour.

3) Email tech support for any laptop manufacturer and be really explicit about what info you need.

However, I contacted Dell loads of times, as each time I spoke to a different person (support personnel based in India) they didn't have a clue and gave me different answers. One said the firewire chipset was made by Dell, another told me the Core2(!) chipset was 32-bit only(!), a third said that "they knew the answer but can't tell me the information I need for security reasons, but I should be assured they used the best firewire components!". Another person was also told by the sales rep they do include TI chipset, and even gave a product number.

All of which are utter shite.

Dell use Ricoh or O2 micro.
Rock use VIA.
Apple were using TI but are (or have done already) phasing in Agere instead.
Asus use Ricoh in some models.
Acer use TI in some models.
Fujitsu use Ricoh or TI.
HP Compaq use Ricoh or TI.
Sony Vaios use TI in many models.

The fw chipset does vary between models/lines, though, so one model/line may use a different fw chipset to another model/line, even though they're made by the same laptop manufacturer. You'd need to check beforehand to make doubley sure.

Only reason I'm anal about it is that I currently use an external mixer and want to tightly integrate it with VST plugins in near realtime (whilst taking care regards phasing issues of course), and Matt mentioned he wanted to achieve low latencies too so thought I'd chip in in case he was involving firewire. Non-TI fw chipsets cannot reliably go below 512 samples (12ms) latency under load, whereas those with TI chipsets can often go as low as 64 samples (1.5ms @ 44.1KHz, or 0.7ms @ 96KHz), which is as good as you're going to get (in the realm of digital audio).

I'm not sure but I think even the older PCMCIA 'cardbus' slots (including the RME multiface, etc.) may do well to be made by TI too. I guess Matt could post on the [RME forum] or the SOS forums to see if cardbus is equally an issue. They're a knowledgable lot over there. "jschild" (Scott of www.ADKProAudio.com) who occasionally posts on the SOS forum is particularly experienced and respected in this field.
