Firewire with Oxford or OHCI ?

Years ago it was critical your firewire card had the "Oxford" specification.
Is this still true? I'm having a hard time finding a card naming "Oxford".
Is OHCI compliant the same thing? Machine is WindowsXP.

Thanks
 
Right. A client here buys everything for the office through www.cdw.com and
I'm having a hard time finding anything with "Oxford" and just wondering if
it is still relevant today. I did find some obscure sites and manufactures
(at least obscure to me) selling devices with "Oxford 922" chips.

Opinions anyone?

It still seems to be the commonest chipset around for firewire/USB.

Often buggy - but there doesn't seem to be an awful lot of choice.

Just ordered a device with a jmicron chipset - external USB with SATA
connection.

Oxford Semiconductor is the manufacturer of a particularly excellent family

Check retailers that specialize in FireWire, for example FireWire Depot
<http://www.fwdepot.com> and WiebeTech <http://www.wiebetech.com>. Their
specs pages usually list the bridge chips used in the enclosures they
sell, as do the enclosure manufacturers' pages -- if the retailer
indicates who makes a particular enclosure.

Oxford Semiconductor <http://www.oxsemi.com/> is the leading name in
FireWire bridges for a reason: their chips tend to have fewer
compatibility problems.
 
Do know that XP wants an OHCI compliant chipset for Firewire.

XP SP1 offers a few Firewire fixes.

Oxford is the most common maker of Firewire/USB connectivity chipsets.

Am using a Firewire card with a Texas Instruments (TI) chipset, OHCI
compliant in one PC. Working in XP, ME, and 98SE. No drivers were
required. 98SE has all the USB/Firewire updates from MS prior to the
install. ME has never seen the internet. XP was SP1, SP2 installed. All
have access to firewire connected hard drive, XP and ME have firewire
networking installed. 98SE does not support this type of network. Using
ME, and VideoStudio for firewire connected camcorder.

Another common OHCI compliant firewire chipset for your purposes is made by
VIA.

That remains to be seen.
Non OHCI compliant cards that come with an XP driver may well work.
Whether such cards actually exist is a completely different matter tho.

[Rant snipped]
 
Did you read the MS link below your response?

Saying what I have firewire operational on a particular PC, or mentioning TI
and VIA as another firewire chipmaker is not a rant in my humble opinion.
