ENTERASYS ROAMABOUT PCMCIA CARDS
The Enterasys cards are common as mud at the moment, as there has
been a flood of them obtained through bulk orders. They are actually
rebadged Lucent Orinoco Silvers with external antenna connectors.

OPERATING SYSTEMS
LINUX
These cards are supported by the built in orinoco_cs.o driver that
comes in 2.4 series kernels (possibly 2.4.5 and later). This driver is
by David Gibson [17] and is also described on the Linux WLAN page [18]
Make sure you upgrade [19] to a more recent version of orinoco_cs, as
the included version is 0.09 or older, and is very buggy.
There is an experimental patch to enable AP mode support for the
orinoco_cs 0.13b driver here [20]. You'll have to load a new Tertiary
firmware on your card for this to have any chance at working.
WINDOWS
Well my flatmate just stuck it in a Win2K laptop and it just
worked... but he had previously installed a Compaq card, I don't know
if that complicated matters?
Another report: Bog standard fresh install of W2k on a lappy with
service pack 3 picked it up no worries, Netstumbler was able to use
it.
Anther reports working cards in Win95 laptop, using drivers from the
Enterasys website.
There are issues on some laptops running Win98 - where the Enterasys
client utility will alternate between saying it can see the card, and
can't see the card, at approx 1 second intervals.
Works fine on ME, in the PCI-riser.
WINDOWS CE
Yes, this card works with Windows CE. I have tested it using a
CompactFlash [21] to PCMCIA adapter on my iPAQ.
email Zeigerpuppy [22] for more info
MAC OS 7/8/9
You can use the Orinoco drivers [23] (same chipset). Fully supported
for 8.6 through 9.2, but ruomor has it they will also work in 7.5.x
and up. You may need to flash the card with Orinoco firmware. Or not.
MAC OS X
Drivers here [24], but have not yet implemented 100% of the features.
BSD\'S
(it's basically the same driver on all three, but here's the specific
manual pages for each) OpenBSD [25] NetBSD [26] FreeBSD [27] see also
the specific cases [28] page for troubleshooting.
FIRMWARE
The default 6.04 firmware only supports the non-standard Ad-Hoc mode,
not true IBSS mode. You'll need to flash the card to 6.06 [29]
firmware or later for IBSS ad-hoc support under linux.
Note that it's the secondary firmware which is flashable.
When using the cards under Windows, the Windows driver loads a
tertiary firmware into volatile memory each time the driver is loaded,
and the secondary firmware is not used at all.
Under linux, however, it's the secondary firmware which is used by
the card.
RogerVenning [30] has successfully used a card in non-upgraded state
(Lucent/Agere firmware version 6.04) under Win2K and Linux to
associate to an Nokia A020 access point. IBSS mode has not been
tested.
Another report has successful use of IBSS mode between two Enterasys
cards (but not interoperability testing with other manufacturers).
That'd be me (TonyLangdon). The network setup at NodeBCJ [31]
comprises a P133 laptop running Red Hat 6.2 with the Enterasys drivers
acting as a wireless router, and the roaming workstation is a Windows
95 laptop running the Enterasys drivers. There were no firmware
upgrades installed. According to the documentation with the drivers,
the linux machine was configured to use IBSS mode, and the Windows
driver can only select IBSS (called Peer-Peer) from the GUI. With IBSS
configured at both ends, the link works perfectly.
Also worth noting that Netstumbler is capable of detecting peer-peer
networks when using the Enterasys cards with stock firmware.
MISC NOTES
RogerVenning [32] has had success with a Netgear MA301 (PLX based)
PCI carrier with these Enterasys cards under Linux. See PlxCarriers
[33] for more information.
The Enterasys cards work well in any PCI carrier which uses a Ricoh
chipset (such as the SVEC WL123).
Note that these carriers supposedly require a PCI 2.2 compliant bus,
but numerous people have got them working under linux with a PCI 2.1
compliant bus (although some stuffing around [34] with interupt and
memory addresses may be required.
