Installation
Installation of the Advansys IEEE1394 card was simple with the necessary drivers for the
adapter card being pulled from Windows 98SE, no additional drivers were required. Thus
installation was a simple matter of disassembling the case, and installing the card in an open PCI slot,
putting things back together and booting up.
Just to re-iterate IEEE1394 devices will only work with Windows 98
Second Edition operating system or later. Apparently Microsoft did not incorporate the appropriate FireWire support in its
earlier OS's, including plain old Windows 98.
Benchmarks
Since we tested this IEEE1394 card by way
of a data transfer test, a combination of Sandra benchmarks and timed
data transfers to an external harddrive were used. In previous tests, discrepancies with the values Sandra reported were noted,
so the timed tests add a useful perspective. The test consisted of
moving 1.9Gb files via the IEEE1394 card to the FireWire based
HotDrive. For comparison, we performed the same tests with the Evergreen IEEE1394 adapter card.

Sandra reported a Drive Index rating
of 5700
for the HotDrive while it was connected through the Advansys IEEE1394
card. This result was about twice as high as with the drive connected via
the adapter card Evergreen ships. |

Sandra
benchmarks with the
reference Evergreen
IEEE1394 card show lower values then previously shown with the Advansys IEEE1394 adapter
Card. |
The timed trials tend to illustrate the how the
data transfers are actually taking place, and give a more palatable Mb/s rating.
A 1.9Gb file was transferred to the external FireWire drive, from two different
internal hard drives, and then between the drives themselves. The duration of the
transfer was then used to find the resulting Mb/s. As the only variable in each of the
tests was the alternating IEEE1394 card, this should serve to illustrate how the data flows
through the individual cards. The data transfer between the two internal hard drives serves
as a reference to illustrate overall all system transfer speeds.

As you can see by the trials, the Advansys IEEE1394 PCI adapter card faired a
bit better in the timed tests than the reference Evergreen IEEE1394 PCI adapter card
did. The benchmarking results from Sandra of data flow through each of the two IEEE1394 cards
show a 2:1 difference in the performance of the HotDrive when connected to
the Advansys IEEE1394 card further emphasizing the point.
As the Advansys IEEE1394 PCI adapter card is based
on a single chip design, procedures appear to be carried
out more efficiently then with the reference Evergreen dual chip design. The
IEEE1394 chipset on the Advansys card is manufactured by Fujitsu and capable
of 100Mbit/s, 200Mbit/s or 400Mbit/s data transfers at a 133Mb/s Host Bus
Data Rate while supporting three IEEE1394 ports.
With out going into too much detail the chipset
combines PHY and OHCI functions into a single device, and supports some nifty
features such as 'look ahead context processing'.
