Speedup Your HDD With Raid

If one fast drive is good, then five working together is surely better.
Redundant Array of Inexpensive Disks (RAID) technology has been a significant lifesaver and performance boost for file servers. RAID can be set up in different configurations to provide systems with fault-tolerance or performance enhancements that are crucial to keeping data safe. It can be applied to personal desktop systems to provide significant disk drive performance enhancement.

RAID-0 (zero) is the most basic and highest performing RAID configuration. Portions of data normally stored on one disk drive are spread out across multiple drives, and those drives are accessed in parallel to deliver the data faster, because each drive does not have to access all of the data before it can be delivered. RAID-0 is unfortunately and by nature the least reliable in terms of data integrity, because a failure in any single drive renders all of the data useless.

In contrast to RAID-0, in a RAID-1 configuration all of the data is stored equally on two drives, in parallel. This slows the storage and reading performance but almost guarantees that the data remains intact even if one of the drives fails.

RAID-5 is somewhat a mix of RAID-0 and RAID-1, striping data across multiple drives but also adding error correction information across the drives, providing the advantages of parallel drives and a high degree of ability to recover data if one drive should fail.

Another hybrid implementation of RAID that is very affordable and intended for desktop system is RAID-0+1. The Promise Technology (http://www.promise.com) FastTrak TX4000 RAID controller card is specifically meant for desktop users with an appetite for high-performance disk systems. Performance enhancements of up to 30% are possible. Upgrading with top-performing disk drives and putting them into a RAID configuration just might knock the dust bunnies out of your keyboard.

The basic steps to install a RAID configuration on your PC are listed below. Be aware that the specific steps will be unique to the RAID controller (system board or add-in card type), your system BIOS, and RAID configuration software. After installation, the RAID configuration should appear to your operating system as a single-disk volume.

You need a RAID controller or RAID capabilities built into your system board. Promise Technologies is one of the most popular brands of add-in RAID controllers for IDE drives.

Have at least two identical disk drives on hand for RAID-0 and 1. Configuration of a simple RAID is a lot easier if the drives are identical: there will be no wasted space, and they should mirror each other and perform equally well. RAID 0+1 will require at least four disks.

If necessary, make a bootable DOS diskette with any necessary drivers or configuration program for your RAID controller. For BIOS-based RAID setups, familiarize yourself with the RAID setup screens and options in BIOS. It is likely you will have to connect the RAID drives to different IDE connections than the normal non-RAID IDE interfaces.

With the system powered down, install and connect the drives to the RAID controller interface connectors.

Start the system and either boot with the DOS diskette containing the RAID controller configuration program or get into the BIOS setup to access the RAID configuration screens.

Select the type of RAID you will be creating—typically 0, 1, or 0+1.

Partition the drives with the configuration program or BIOS screens. This process establishes how the RAID controller views and uses the drives.

When RAID controller configuration and disk partitioning is complete, you will either FORMAT the drives under DOS or start the installation of your operating system onto the new RAID system as the primary boot drive.

(RAID 1 and higher only) To test your configuration after installing your operating system, shut down and disconnect one of the RAID drives, then restart to verify that indeed the RAID system actually mirrors data to one of the drives.

How To Byepass BIOS Passwords : The Smart Way

Introduction to BIOS Passwords

The best method to reset a BIOS password depends on what BIOS the computer has. Common BIOS's include AMI, Award, IBM and Phoenix. Numerous other BIOS's do exist, but these are the most common.
Some BIOS's allow you to require a password be entered before the system will boot. Some BIOS's allow you to require a password to be entered before the BIOS setup may be accessed.
The general categories of solutions to reset a BIOS password are:

• Using a Backdoor BIOS Password
• Resetting the BIOS Password using Software
• Resetting the BIOS Password using Hardware
• Vendor Specific Solutions for resetting the BIOS Password

Using a Backdoor BIOS Password

Some BIOS manufacturers implement a backdoor password. The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.

AMI Backdoor BIOS Passwords

Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.

Award Backdoor BIOS Passwords

One reported Award backdoor BIOS password is eight spaces. Other reported Award backdoor BIOS passwords include 01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT, CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332, J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz, TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.

Phoenix Backdoor BIOS Passwords

Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.

Backdoor BIOS Passwords from Other Manufacturers

Reported BIOS backdoor passwords for other manufacturers include:

Manufacturer	BIOS Password
VOBIS & IBM	merlin
Dell	Dell
Biostar	Biostar
Compaq	Compaq
Enox	xo11nE
Epox	central
Freetech	Posterie
IWill	iwill
Jetway	spooml
Packard Bell	bell9
QDI	QDI
Siemens	SKY_FOX
SOYO	SY_MB
TMC	BIGO
Toshiba	Toshiba

Remember that what you see listed may not be the actual backdoor BIOS password, this BIOS password may simply have the same checksum as the real backdoor BIOS password. For Award BIOS, this checksum is stored at F000:EC60.

Resetting the BIOS Password using Software

Every system must store the BIOS password information somewhere. If you are able to access the machine after it has been booted successfully, you may be able to view the BIOS password. You must know the memory address where the BIOS password is stored, and the format in which the BIOS password is stored. Or, you must have a program that knows these things.
You can write your own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that you wish to read in port 0x370, and then reading the contents of port 0x371.
!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.
CmosPwd will recover the BIOS password for the following BIOS versions:

• ACER/IBM BIOS
• AMI BIOS
• AMI WinBIOS 2.5
• Award 4.5x/4.6x/6.0
• Compaq (1992)
• Compaq (New version)
• IBM (PS/2, Activa, Thinkpad)
• Packard Bell
• Phoenix 1.00.09.AC0 (1994), a486 1.03, 1.04, 1.10 A03, 4.05 rev 1.02.943, 4.06 rev 1.13.1107
• Phoenix 4 release 6 (User)
• Gateway Solo - Phoenix 4.0 release 6
• Toshiba
• Zenith AMI

Resetting the BIOS Password using Hardware

If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.
On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.
If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.
Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it.
RTC's which require external batteries include:

• Dallas Semiconductor DS12885S
• TI benchmarq bq3258S
• Motorola MC146818AP
• Hitachi HD146818AP
• Samsung KS82C6818A

Most RTC chips with integrated batteries can be reset to clear the BIOS password by shorting two pins together for a few seconds.
You will see more than one option for some chips due to testing by various people in the field. Remember to remove power from the system before shorting these pins.

RTC Chip	Pins
Dallas DS1287ATI benchmarq bp3287AMT	3 (N.C.) and 21 (NC/RCL)
Chips & Technologies P82C206	12 (GND) and 32 (5V)-or-74 (GND) and 75 (5V)
OPTi F82C206	3 and 26
Dallas Semiconductor DS12887A	3 (N.C.) and 21 (RCLR)

You should be able to discover how to reset the BIOS password stored in most RTC (Real Time Clock) chips by reading the manufacturers data sheet for that RTC. Some RTC's, like the Dallas DS1287 and TI benchmarq bq3287mt cannot be cleared. The solution to resetting the BIOS password on systems with those RTC's is to purchase a replacement RTC chip. How inconvenient!
