How do I work with ?Advanced RISC Computer (ARC) names??

What are the two sections labeled [boot loader] and [operating systems] in the BOOT.INI (read only, system, hidden)?

1. The [boot loader] section supplies timeout interval after which the default operating system to load (defined in the default= line that follows timeout) loads automatically. *Windows NT usually boots from (boot loader) section.

2. The [operating systems] section supplies complete menu of operating system choices NTLDR displays after the program loads. You can disable the timer before it elapses by pressing any arrow or letter key on the keyboard. Then, you can wait as long as you like to make your menu selection. *Windows NT boots from (operating system) section if deliberate change to OS is made.

Note: You need to make changes in both especially if using disk mirroring or disk duplexing and one fails. 

Remember

• Boot files reside on the System Partition. (System partition is c:\ for DOS). NT system partition must be a primary partition.
• System files reside on the Boot Partition. (Boot partition is where your OS is located). Can be primary partition or logical drive.
• Very Microsoft of them :-)

I. How do I determine if I use the Multi or SCSI parameter?

1. "SCSI" only applies to a SCSI drive whose onboard BIOS has been disabled (no BIOS translation capabilities).
2. If the Ntbootdd.sys file is on your system, use "SCSI".

If  neither is the case, use "multi."

II. How do I determine the SCSI or Multi number?

What is a disk controller - a chip and associated circuitry that is responsible for controlling a disk drive. There are different controllers for different interfaces. For example, an IDE interface requires an IDE controller and a SCSI interface requires a SCSI controller.

Which Disk Controller is the drive we are looking for attached to?

A. If there is only 1 Disk controller (multi or SCSI) = 0
B. If there are 2 Disk controllers (multi or SCSI) = 1 ; this is assuming the hard drive we are looking for is attached to the second controller. If the hard drive we are looking for is attached to the first disk controller (multi or SCSI) will = 0

III. How do I determine the rdisk and disk number?

Part 1

1. If we are using "multi", "disk" will always be 0
2. If we are using "scsi", "rdisk" will always be 0

Part 2

A. disk = SCSI bus ID (usually 0 to 6) when "SCSI" is chosen.
B. rdisk = LUN (SCSI logical unit number) or position in disk chain when "multi" is chosen. Usually
-The first hard disk = 0
-The second hard disk = 1
-The third hard disk = 2
-and so on unless specifically mentioned.

IV. How do I determine the partition number?

1. Caveat: *NT assigns partition numbers to all primary partitions before assigning numbers to logical drives within extended partitions

Example:

2. Caveat: *If you create another primary partition, regardless of hard disk it is created on, new primary partition receives lower # than any logical drive on an extended partition

Example:
