I have a system with an onboard ethernet controller, the above mentioned PCNet32/Home device. Instead of using the two onboard PHY's, there is an external 10/100 PHY. Both are detected by the kernel, but in the wrong order. As such, the pcn device fails because it can't find any MII PHY's, and a few devices later, finds ukphy0 Here is the dmesg output: root@whitetower.gambrl01.md.comcast.net:/export3/src/sys/compile/xterminal Timecounter "i8254" frequency 1193182 Hz CPU: AMD-K6(tm) 3D processor (267.28-MHz 586-class CPU) Origin = "AuthenticAMD" Id = 0x58c Stepping = 12 Features=0x8021bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,PGE,MMX> AMD Features=0x80000800<SYSCALL,3DNow!> real memory = 31457280 (30720K bytes) avail memory = 27189248 (26552K bytes) Preloaded elf kernel "kernel" at 0xc0383000.

Any help would be appreciated, but keep in mind that this is a single board computer - and the resources are locked. The BIOS can only modify the ATA controllers, boot options and POST level.
