iPod Diagnostic Menu

 

Memory:	The Memory tests include diagnostic procedures for your iPod’s SDRAM, IRAM and FLASH memory.    SDRAM: The RAM memory test. The SDRAM Fulltest will take several minutes. A successful pass result is “SDRAM OK.” IRAM: Not sure exactly what this test does. It takes several moments to load before running a quick test and rebooting your iPod. FLASH: This test will do a checksum test of your iPod’s flash memory.
IO:	Comms: This tests the communication ports of your iPod including USB, FireWire and Remote. If the Remote is not connected to your iPod at the time of the test, you can expect a NG (no good) for the HP (headphone-port).    Wheel: This option has two tests, Keytest and Wheeltest. Push each button once to pass the Keytest. The Wheeltest just gives you a coordinate of where your finger is on the Click-Wheel. : This option has two tests, Backlight (0 to 255; 128 is the default) and Color. Much like a VRAM test, the Color test will run through a series of colors, patterns and gradients. HeadphoneDetect: This test checks the Hold Switch and Headphone port. HardDrive: This option has four tests. HDSpecs will tell you everything from hard drive temperature to serial number. HDScan scans your iPod’s hard drive. This is a great way to see if you have a healthy iPod and if your hard drive is fragmented. This test will take a few minutes so be patient. HDSMARTData returns SMART data for professional repair applications and personnel. HDRW tests the ability of your hard drive to RW (read and write data). A FAIL result probably means you need to get your hard drive replaced. Audio: This option has two tests. Playback plays an audio sample to make sure your iPod can produce sound. MIC tests your iPods ability to record audio.
Power:	A2DTests: This test has multiple sub tests.    PhilipsID checks the power system of your iPod A2D lists a series of A2D (analog to digital) tests.
Status:	Status displays the status of several of your iPod’s key systems.    Sharp: LCD screen HP: headphones. Are they connected? [0 = no, 1 = yes] FWPWR: FireWire power. Is your FireWire cable charging your iPod? USBPWR: USB power. Is your USB cable charging your iPod?
SysCfg:	SysCfg: System Configuration.    This lists your iPod’s hardware version, serial numbers, and part number.

Internet Protocol

IP Explained

 

IP Address (Internet Protocol Address): This number is an exclusive number all information technology devices (printers, routers, modems, et al) use which identifies and allows them the ability to communicate with each other on a computer network. There is a standard of communication which is called an Internet Protocol standard (IP). In laymans terms it is the same as your home address. In order for you to receive snail mail at home the sending party must have your correct mailing address (IP address) in your town (network) or you do not receive bills, pizza coupons or your tax refund. The same is true for all equipment on the internet. Without this specific address, information cannot be received. IP addresses may either be assigned permanently for an Email server/Business server or a permanent home resident or temporarily, from a pool of available addresses (first come first serve) from your Internet Service Provider. A permanent number may not be available in all areas and may cost extra so be sure to ask your ISP.

Domain Name Server (DNS): This allows the IP address to be translated to words. It is much easier for us to remember a word than a series of numbers. The same is true for email addresses.

For example, it is much easier for you to remember a web address name such as whatismyip.com than it is to remember 192.168.1.1 or in the case of email it is much easier to remember anonymous@whatismyip.com than anonymous@192.168.1.1

Dynamic IP Address: An IP address that is not static and could change at any time. This IP address is issued to you from a pool of IP addresses allocated by your ISP or DHCP Server. This is for a large number of customers that do not require the same IP Address all the time for a variety of reasons. Your computer will automatically get this number as it logs on to the network and saves you the trouble of having to know details regarding the specific network configurations. This number can be assigned to anyone using a dial-up connection, Wireless and High Speed Internet connections. If you need to run your own email server or web server, it would be best to have a static IP.

Static IP Address: An IP address that is fixed and never changes. This is in contrast to a dynamic IP address which may change at any time. Most ISP’s a single static IP or a block of static IP’s for a few extra bucks a month.

IP version 4: Currently used by most network devices. However, with more and more computers accessing the internet, IPv4 addresses are running out quickly. Just like in a city, addresses have to be created for new neighborhoods but, if your neighborhood gets too large, you will have to come up with an entire new pool of addresses. IPv4 is limited to 4,294,967,296 addresses.

IP version 5: This is an experimental protocol for UNIX based systems. In keeping with standard UNIX (a computer Operating System) release conventions, all odd-numbered versions are considered experimental. It was never intended to be used by the general public.

IP version 6: The replacement for the aging IPv4. The estimated number of unique addresses for IPv6 is 340,282,366,920,938,463,463,374,607,431,768,211,456 or 2^128.

The old and current standard of addresses was this: 192.168.100.100 the new way can be written different ways but means the same and are all valid:

* 1080:0000:0000:0000:0000:0034:0000:417A

* 1080:0:0:0:0:34:0:417A

* 1080::34:0:417A
