Operating System Support
The drivers for the SysKonnect SK-98xx V2.0 Gigabit Ethernet Adapte rs support the following oper-
ating systems:
• Windows NT 4.0, Windows 98 Second Edition, Windows Millennium Edition, Windows 2000,
and Windows XP
• Linux kernel 2.2.x and 2.4.x
• Novell NetWare 4.20 or higher, Novell NetWare 5 and 6
• Sun Solaris 7, 8, and 9 on SPARC systems as well as Solaris 7 and 8 on X86 systems
• IBM AIX 4.3.3, AIX 5.1, and AIX 5.2
• HP-UX 11.00 (PA-RISC 32/64-bit), HP-UX 11.11 (PA-RISC 64-bit), and HP-UX 11.20 (IA-64)
High Performance
The SysKonnect SK-98xx V2.0 Gigabit Ethernet Adapters are high performance and highly reliable
adapters. Best performance is reached with a 64-bit/66 MHz bus. In full-duplex mode, wire speed
can be achieved.

Jumbo Frames

The SysKonnect SK-98xx V2.0 Gigabit Ethernet Adapters support 9 KB Jumbo frames. They are
tested according to the prevailing standard and switches on the market.

TCP, UDP and IP checksum calculation

The adapter supports the calculation of TCP, UDP, and IP checksums. These calculations are inte-
grated in the hardware of the Gigabit Ethernet adapters. The checksums ar e calculated without time
loss by the MAC controller for both the receive and the transmit path. This improves the overall per-
formance of the system and shifts these CPU-intensive tasks away from the host CPU.

Dynamic Interrupt Moderation

If the network is running at gigabit speeds and small packets are being transferred, there may in ex-
treme cases be more than 100,000 interrupts per second. To reduce the load on the CPU, the Giga-
bit Ethernet adapters can use interrupt moderation to group these interrupts so that several data
packets can be handled per interrupt.
For more information, refer to the White Paper “SK-NET GE G igabit Ethernet Server Adapter”,
which can be found on the installation CD-ROM and on our web site.
Promiscuous Mode / Multicast Support
The SysKonnect SK-98xx V2.0 Gigabit Ethernet Adapter supports promiscuous mode for analyzers.
The adapters support multicast for special applications, which use mu lticast addresses. In addition,
two unicast addresses are supported by the hardware. By default , the promiscuous mode is turned
off.
