A Management Controller (MC) or Baseboard Management Controller (BMC) usually requires
Ethernet connectivity for remote management. Initially, MC’s had a dedicated Ethernet port
to achieve this connectivity.
Later, Ethernet manufacturers started using proprietary sideband interfaces to provide a
mechanism by which the MC could share an Ethernet port with the Operating System. This
interface was generally based upon the I2C/SMBus interface, but had a proprietary protocol.
The DMTF set out to create an industry standard sideband interface that would operate at a
much greater speed than SMBus and alleviate some of the burden on BMC engineers who,
for years, had been writing different Ethernet code based on which manufacturers’ Ethernet
device was used as the LOM (LAN on Motherboard) for the server board.

最近在朋友买了一个二手的DELL C1100(CS24-TY) 机架式服务器。
注意CS24-TY是DELL C1100的定制型号，和标准版的有所不同。但是网上玩家已经试出了更新标准版BIOS和BMC的方法(见下面英文介绍的步骤)。不过我嫌麻烦，没有做CMOS放电的步骤，也成功了。
-------------------------------------------------------------------------------------------------
I want to write this guide because a lot of people are getting the C1100 off of Ebay or other sources and trying to update firmware but having trouble.
So you botched up the BMC firmware update?
The orange/amber light is blinking and blue light is on and the power button does nothing?
The C1100 is stuck at amber orange blinking light?
Open up your C1100 (powered off)
Close to where the PCI-E card is, somewhere on the motherboard there are a few jumper. On particular one, should say something like CLR CMOS.
Put the CLR CMOS so that its its on the other two pins from what it originally was.
Put the power cord in, wait 10 seconds, Pull the power cord.
Put the CLR CMOS jumper back to original position.
CAREFUL: THE FANS WILL GO AT FULL THROTTLE
Put the power cord back in. The fans will go at full throttle.
Now wait for like 5 or so minutes! Plug in your monitor, keyboard and USB Bootable Thumbdrive with DOS and firmwares (see below).
It will first say CMOS and BMC not responding, loading defaults etc and restart. Wait another 5 minutes, press F11 to get the BBS Priority and choose your USB thumb drive.
If you pull the power cord at any other moment, you will have to redo the CLR CMOS to boot up again.
Getting the BIOS and BMC Files together:
Get DOS on USB (search for Rufus, find on github or google,制作成freedos启动盘)
Get the latest BIOS B25
Get the latest BMC 1.86
Put it all in directory of the usb flash drive (make sure directory less than 8 characters)
Updating the BIOS:
Boot to DOS
Find the BIOS directory ( I called mine b25)
Enter command AFUDOS .ROM /P /B /K /X
This is the same as the F.BAT file that comes from dell but with
