Dell Server Poweredge | What is the difference between Drivers and Firmware?

What is the difference between Drivers and Firmware? On a server, you can update drivers and firmware. A device driver is a particular form of a software application that is designed to enable interaction with hardware devices. Without the required device driver, the corresponding hardware device fails to work. Device drivers are operating system-specific and hardware-dependent. It acts as a translator between the hardware device and the programs or operating systems that use it. Note: Drivers are Operating System specifics. Firmware is a software program permanently etched into a hardware device such as keyboards, hard drive, BIOS, or video cards. It is programmed to give permanent instructions to communicate with other devices and perform functions like basic input/output tasks. Firmware is typically stored in the flash ROM (read only memory) of a hardware device. It can be erased and rewritten. Keep a server up to date is important to have the best interoperability ...

Dell R430, R530, R630, R730, R830, R930, M630, M830, FC430, FC630, FC830, T630 PowerEdge Servers may reboot after experiencing "Correctable memory errors"

Description When the issue with Dell R430, R530, R630, R730, R830, R930, M630, M830, FC430, FC630, FC830, T630  PowerEdge Servers may reboot after experiencing "Correctable memory errors" .  This has only see in BIOS version 2.3.x. Example: MEM0701 Warning Correctable memory error rate exceeded for DIMM_xx. MEM0702 Critical Correctable memory error rate exceeded for DIMM_xx . Life Cycle  Log example: 2017-03-07 23:08:02 SYS1003 System CPU Resetting. 2017-03-07 23:08:02 SYS1001 System is turning off. 2017-03-07 23:08:02 MEM0702 Correctable memory error rate exceeded for DIMM_xx. Solution This has primarily been reported in R630 and R730.  The potential exists in all of 13G though, with BIOS version 2.3.x. A change was introduced in BIOS version 2.3.x for additional logging to SPD which introduced this particular issue. The Q1 BIOS versions for the affected platforms fixes this server reboot in conjunction with a correctable error...

How to make the calculation from Hexadecimal to Decimal

Objective How to make the calculation from Hexadecimal to Decimal Steps Hex is a base 16 number and decimal is a base 10 number.   Reference the hexadecimal to decimal chart below to determine the decimal equivalent of every hexadecimal digit.  Here are the steps to convert hexadecimal to decimal: Get the decimal equivalent of hexadecimal value from chart below. Multiply every digit with a 16 power based on the digit location. (zero based, 7DE: E location is 0, D location is 1 and the 7 location is 2) Sum all the multipliers. Here is an example: 7DE is a hex number 7DE = (7 * 16 2 ) + (13 * 16 1 ) + (14 * 16 0 ) 7DE = (7 * 256) + (13 * 16) + (14 * 1) 7DE = 1792 + 208 + 14 7DE = 2014 (in decimal number) 16 Bit Factor Table: 16 0 = 1 16 1 = 16 16 2 = 256 16 3 = 4096   Decimal System Decimal number system is the most commonly used and the most familiar one to the general public.  It is also known as...
