[LinuxBIOS] Is this system supported? SUN FIRE X4100

[Lu, Yinghai]

1. Is there anything special in BIOS to be done for making serial over
LAN or IPMI over LAN working with your BMC daughter card...? I mean
connection to NIC shared or I2C.
2. Good to hear that separated FLASH for LSI...
3. Can you check the protocol for USB that BMC simulated? OHCI or UHCI
or EHCI only?

Nothing required IIRC, but optional features such as the boot
mailbox are available.  The service processor does not have
an RTC so it relies on the BIOS to set its time with Set SEL
Time command but this could be easily done after boot with
the OpenIPMI driver and ipmitool script.

Flash of system BIOS can be done through the service processor
as it has hooks into the LPC bus (system must be in reset for
this to work).  This means a LinuxBIOS port would not be overly
dangerous since you can always flash a working BIOS by reloading
SP firmware (which includes a system BIOS).

LSI firmware is on a separate flash.  Disk boot will be tricky
but getting network boot working should be easier.  Boot over
redirected USB via service processor might also work...
