For the update4 (20060605) distro, the kernel version is 2.6.9-39, so the buslogic driver on VMware’s site doesn’t work anymore. You can use the one attached, but it’s not supported by VMware. Install Linux by following the instructions on their site.
This is obviously not supported by VMware, Inc. There’s also no guarantee that your VM will be stable, but I’d bet that it would be.
