version 2EKT46A

Fixes a problem with the USB key for dictation software.

version 2EKT45A

• Security Enhancement

version 2EKT44A

• Fixes the intermittent POST 162 error with specific processors
• Fixes weekly power on event in Setup

version 2EKT43A

• Updates BIOS support for the Pentium D D0 step processor

version 2EKT42A

• Updates BIOS processor support

version 2EKT41A

• Updated flash2.exe. BIOS level 40 introduced a fix which has a side effect of making it impossible to flash to a down-level BIOS (from 40 or above to 37 or below). The updated flash2.exe allows this down-level flashing to occur again. After creating a down-level diskette, replace the flash2.exe program on the down-level diskette with the one from this release. It remains impossible to use winphlash to do this. Note that boot-block recovery is able to flash to a down-level BIOS.

• Fixes a problem where the system hangs on resume from standby with some PCI-E graphics cards. This problem was introduced in BIOS level 37.

version 2EKT40A

• Sets an upper bound for the detected nominal processor temperature

version 2EKT39A

• Adds a workaround for one specific PCIe RAID adapter
• Fixes a problem with a certain video capture card
• Adds a BIOS setup option to disable the internal graphics device (IGD). If this is done inadvertently, the clear CMOS jumper will re-enable the device.
• Updates the fan control for 65nm Intel processors
• Incorporates Intel microcode updates for CPUID 0F65h

version 2EKT37A

• Fixes a problem where the system hangs or displays a POST error for PCI-Express graphics adapters having multiple bridges

• Correctly identifies dual-core CPUs as having two phsyical cores, instead of one physical and one logical
• Changes USB keys power-on-password security mode from "Hard Disk" to "Removable" in the "Security Profile by Device" setup screen
• Fixes problems with PCIe x4 RAID adapters
• Enables over-current sensing pins on the front USB connector
• Removes residual voltage from VCC on the USB connectors

version 2EKT33A

• Fixes a problem where the system crashes after executing a 3D screensaver without HyperThreading, will now not allow C2 state with processors that only support C1
• Adds Dutch translation for Fan Acoustics help text
• Fixes a problem where the IDE drive password cannot be set for certain passwords (like "2PHKKU")

• Revised fan control gives a separate cooling profile for each board ID, plus special handling of multi-core processors

version 2EKT32A

• Ensure that the Triangle Operation Region field gets filled in
• Allows the system to perform a warm boot when Ctrl+Alt+Del is pressed
• Ensures that boot audit recording feature records CD-ROM boots
• Ensures that POST 1806 errors are logged in SMBIOS
• Greys out password change option in setup when the system has a password entered and Setup was entered without entering a password
• Removes incorrect text from the Setup help text
• Updates the security algorithm for the hard drive password

version 2EKT31A
