Once Windows and Linux gets running there are so few BIOS calls it's not funny anymore. I'm going to guess this is not about audio production. Tell more and no, I've yet to see any discussion that tests this. In fact, how about you sharing a test so folk can get you a standard result?

Supply a link to the DPC Latency Checker for you to collect results.

well, first of all, i don't have lots of hardware experience.
and i really need a pick from the list. but don't know which of them.
in fact i have new a pcmcia sound card with a new (old) great sound interface (multiface rme).
the problem:
i need perfect sound, that's my job.
no audio problems. and i know (i was told) Dell is quite famous for their lame BIOS development and the ignorance against audio related requirements (low DPC values etc), especially on older units like the latitude. i knew about some multiface owners ex-Dell users who spent a lot of time without knowing the real interface potential.
i almost bought a dell d620 unit, a great old horse, but it'd possibly bring me bad times, and no perfect quality of the interface performance.
i just need to know what unit from the list is the better in terms of what i'm seeking.

Good hunting.

All those are likely to be in folk's closets or such. We just had a discussion about audio capture at a link to follow. DPC latency is a non-issue since we use other than a PC for that. I'm guessing there is some reason why you are looking to laptops from generations ago. Anyhow, good hunting and be sure to supply the test tool you want folk to use. The other discussion link follows.

yes i hear you

In reply to: Good hunting.

but in fact, what i'd need to know to simplify is:
which one of those brands (i mean the brands themselves, not the units - whose i can find 2 handed) has best sound tradition, and a perception (among users) of bringing its users good quality sound and good "character" in contact with interfaces and more advanced stuff of sound?
i am a musiccian, but i barely use laptops (til now).
and the card i got is PCMCIA (so, i depend on that: unveil what would be the more trustable brand in these terms).
btw would you mind bringing it to your son?

My son would never see such a laptop.

I think all the gear there is from the post-PCMCIA generation. You are dealing or diving into the past here so all I can do is ask for you to clarify to others exactly how to measure that DPC latency then chat about newer technologies and how PCMCIA is pretty much old tech.

In fact you can see why PCMCIA is such a drag when you look at how it was based on 8 MHz ISA architecture. That could be slower than USB 2.0! That's really old stuff. I can't guess why you are stuck with PCMCIA but hey, everyone has their reasons.

yes i have!
by krashminded / April 2, 2014 3:47 AM PDT

that's beacause my interface connection depends on a PCMCIA port when plugged into a laptop.

what i need to do is:

among lenovo, acer, vaio and dell:

which one used to offer best sound, which one has the best tradition in terms of audio?

That's why you post in a few forums and detail how to!

In reply to: yes i have!

I don't have any of those machines. Well I do have access to a Compaq R3000 with the single core AMD 64 but that's so old it's never pulled from storage except to update a client's apps. (XP SP3, VB6, etc!)

I wonder why after all these posts details are missing about how to test that latency so others that may have such a laptop can get you some numbers.

At the office we have a lot of laptops.

But PCMCIA slots are gone. Not one laptop takes such a card. I did find a DPC Latency Checker online and tried it. It said the 2 laptops I tried were fine. But what makes me wonder is your odd choice of such old machines. Seems that folk today would use newer gear without trouble. I know my son does. He's an audio engineer at a film production house.
