The driver for Adaptec 7899 chips is "ad160" and is included in OSR506
and 507.  The driver for the Intel SRCU32 is "iir" and is included in
507.

507 does not yet support hyperthreading.  Support is under development.
Out of the box, 507 supports this hardware better by having the "iir"
driver built in.  The driver for the onboard Intel NIC is called "eeG"
and hasn't been released from SCO yet (early Intel releases are floating
around out there; we haven't been able to get them to pass our NIC test
suites yet).

When "eeG" is released by SCO, it will apply to 506 as well as 507.
When hyperthreading support is released, it will apply only to 507.

Also note that to use 506 on any P4-family CPU, you must install at
least rs506a and oss648a.

So for full support, it's:

  OSR506 + rs506a + oss648a + "iir" [ + future "eeG" - no hyperthreading
    support forthcoming ]

  OSR507 [ + future "eeG" + future hyperthreading support ]
