I then setup Boot Magic to allow booting from either the Linux or Windows 98 partitions. The rest of the installation went without a hitch. Since I hoped to use the previously configured Boot Magic for booting, I didn't run the LILO installation. The Boot Magic recovery disk reported the same error. The Partition Magic recovery disk allowed me to reboot into Windows 98, so the partitions seemed ok.
More recent kernels support the network card directly.
The computer came with a DEC 21143 network interface card pre-installed, which Linux was unable to detect. The de4x5 driver didn't recoginize the codes reported by the card. While it is possible to modify the driver and force recognition of the card, the driver in more recent kernels fix the problem. The SuSE 6.X distribution includes the updated Mach64 driver. The 5610 uses the 3D Rage LT PRO video controller supported by the most recent version of the Mach64 driver that you must download from the XFree86 group.
