I tried booting a kernel on the FSG3 once again.
The board will power from both 5V and 12V supply voltages, this is
mostly to deal with driving a PATA drive.
The default Redboot config can be rewritten with fconfig -l, which is
useful -- it expects to load a Linux zImage style kernel from the first
partition, see here:
http://www.nslu2-linux.org/wiki/FSG3/FisCmds
It is necessary to hold down the config reset button at the back to get
Redboot to init the network ports. You need to CTRL-C it to stop it
loading a recovery Linux kernel image.
Kernel config is mostly as per NSLU2, but with some twists.
There is an onboard Via VT6421A SATA/PATA controller, and an NEC EHCI
controller, however neither of them appear to probe on the PCI bus. it
looks like neither of them are activated by the firmware so they most
likely need to have base addresses set up from scratch by the PCI code,
something I believe we don't yet support?
It appears the PHY on board should be supported by the "rlswitch" driver.
I keep getting this even with full miibus compiled in:
%%%

I've tried forcing the PHY numbers to what's in a Linux dmesg (5 and 4
respectively), hints look like this:
%%%
hint.npe.0.at="ixp0"
hint.npe.0.mac="A"
hint.npe.0.mii="A"
hint.npe.0.phy=5
hint.npe.1.at="ixp0"
hint.npe.1.mac="B"
hint.npe.1.mii="A"
hint.npe.1.phy=4
%%%
No joy, even if I switch the PHY numbers around.
Which datasheets am I going to have to look at? ...
I've attached a boot.log for the curious.
cheers
