Operating System Support

The drivers for the SysKonnect SK-98xx V2.0 Gigabit Ethernet Adapters support the following
operating 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
integrated in the hardware of the Gigabit Ethernet adapters. The checksums are calculated
without time loss by the MAC controller for both the receive and the transmit path. This im-
proves the overall performance 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 extreme cases be more than 100,000 interrupts per second. To reduce the load on the
CPU, the Gigabit 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 Gigabit Ethernet Server Adapt-
er”, 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 an-
alyzers.

The adapters support multicast for special applications, which use multicast addresses. In ad-
dition, two unicast addresses are supported by the hardware. By default, the promiscuous
mode is turned off.
