X8OBN_261 Firmware 2.61 8/9/12
1. Synopsis: Change CPU MB 1.1V sensor high threshold to 1.4V for SDIII [SMCDevice.c]
   Description: Change CPU MB 1.1V sensor high threshold from 1.126/1.134/1.142 to 1.4/1.408/1.416 (NC/CT/NR)
   Validation: Check CPU MB 1.1V sensor high threshold through SDIII

X8OBN_260 Firmware 2.60 8/1/12
1. Synopsis: Change CPU MB 1.1V sensor high threshold to 1.4V [SDR.dat]
   Description: Change CPU MB 1.1V sensor high threshold from 1.126/1.134/1.142 to 1.4/1.408/1.416 (NC/CT/NR)
   Validation: Check CPU MB 1.1V sensor high threshold through web or ipmitool 

X8OBN_259 Firmware 2.59 2/14/12
1. Synopsis: Fix test e-mail alert bug
   Description: System will send out "Dummy test e-mail alert" when system power up/down
   Validation: Power up system, boot into OS and shot down

X8OBN_258 Firmware 2.58 1/20/12
1. Synopsis: Fix +5V and +12V voltage sensor high/low threshold values [SDR_X8OBN.dat]
   Description: +5V and +12V voltage sensors show wrong high/low threshold values at v2.57
   Validation: check the sensor high/low threshold either through web or ipmitool

X8OBN_257 Firmware 2.57 7/26/11
1. Changed all Vcache voltage sensors high threshold from 1.112V/1.12V/1.128V to 1.488V/1.496V/1.504V as non-critical/critical/non-recoverable
Description: Vcache high threshold now is 1.488V/1.496V/1.504V
Validation: Check the Vcache high threshold on web 

X8OBN_256 Firmware 2.56 3/31/11
1. New fix for LAN1 fail on ON/OFF and SEL script stress test issue.
Description: Solved the problem to pass the LAN1 on/off test over 3000 times
Validation: Let the system run on/off test script through LAN1 (instead of dedicate LAN) and see whether it passes 3000 times
P.S. 
1. Please discard the firmware v2.06. It is for internal test purpose. 
2. To PM, please don't put the 2.06 release note on test request. 

X8OBN_255 Firmware 2.55 3/9/11
1. Fixed LAN1 On/Off test failure issue
2. Fixed the SEL-unknown errors (NO. 27046) and different event logs between web and IPMIView (NO. 27627) issues

X8OBN_254 Firmware 2.54 2/10/11
1. Fixed false +12V sensor event log issue (NO. 26813)
2. Programmed the memory configuration to set video memory size back to 16 MB 
3. Removed the extra SEL information in assertion event for upper non-recoverable going low  
4. Fixed the SEL logging time error. Previous it used the BIOS time even enable NTP time server in IPMI website
5. Solved the Https port modification fault

X8OBN_253 Firmware 2.53 2/3/11
1. Fixed the chassis intrusion redundant log events (NO. 27145)
2. Solved the SD3 chassis intrusion issue (NO. 27146, 27246, 27247)
3. Solved time error in event logs (NO. 27263)

X8OBN_252 Firmware 2.52 1/24/11
1. Solved redundant sensor event logs (NO. 26813)
2. Solved SD3 polling wrong sensor data
3. Fixed chassis intrustion function (NO. 27145)

X8OBN_251 Firmware 2.51 1/14/11
1. Fixed redundant sensor event logs (NO. 26813)
2. Removed System MAC Address 1 & 2 on System Information web page (temporary) (NO. 26892)

X8OBN_250 Firmware 2.50 12/28/10
1. Modified memory configuration setting for system stability
   Memory table: 
2. Integrated RADIUS authentication feature

X8OBN Firmware 1.05 11/15/10:
1. Fixed +5V, +12V sensor high/low threshold value (NO. 25600)
2. Supported SD3 (NO. 25549)
3. Fixed LAN select not working issue. Please issue -force-boot option when using yafukcs/yafuflash
4. Changed memory speed from hardware strapping to 180 MHz (fixed)
   This one is required to do AC power cycle when update from old one (before 2.0) to new one (after 2.0).
5. LAN configuration preserved when firmware is refreshed

X8OBN Firmware 1.03 11/8/10:
1. Fixed no chassis intrusion sensor issue
2. Changed voltage calculation fomula to fix +5V, +12V voltage issue
3. Fixed the incorrect sensor name displayed on IPMI Trap Receiver
4. Fixed the incorrect voltage sensor number and naming between BIOS and IPMI

X8OBN Firmware 1.01 11/1/10:
1. Fix CPU6 FBD0 show not available issue
2. Fix no fan sensor issue.

X8OBN Firmware 1.00 10/20/10:
