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 NAME>.ROM /P /B /K /X
This is the same as the F.BAT file that comes from dell but with the /X. The /X is important because it tells to ignore ROM ID
Wait to finish (DON'T RESTART YET, DO THE BMC Firmware Update)
Note: nothing critical, it's just that I did mine one after the other and it worked.
Updating the BMC:
You have to edit the batch file and move some files around before you put it on the USB thumb drive.
Copy the FIRM.BIN to the DOSFLASH directory in SOCFLASH directory.
Edit the dosflash.bat file:
socflash cs=2 option=fc if=firm.bin skip=0x200
The firm.bin is now in the same directory as socflash.exe.
Now you should be right after the BIOS Update from above.
Go to your BMC directory -> SOCFLASH -> DOSFLASH
Run the dosflash.bat file.
Give it a few minutes and you should be good.
Now after a minute of waiting just pull the power cord, wait a few seconds for complete power down and plug it back in. Give it a few minutes and you should be golden.
-------------------------------------------------------------------------------------------------
这是标准版C1100的最新BIOS(S99C3B25)和BMC(1.86)：
首先执行F.BAT强刷Bios，然后不要重启服务器，执行dosflash.bat刷BMC。
