Install the USB flash drive into an open USB port of the system
Ensure a Monitor and keyboard are connected to the system
Power the system on, or reboot it if already powered on
While the system is booting, alternate pressing F10 and F11 on the keyboard to enter the One Time Boot Menu
This key differs between different appliances, some require F10, some require F11
The BIOS in some systems may be configured to boot from an attached USB device first automatically and require no key-press
Select the install USB flash drive from the list of available boot options
You should see a menu similar to the one below once the drive has booted, with a timer counting down from 60 seconds
If the timer expires, the system will cancel the boot of the USB flash drive and continue a normal system boot

Installation Step-by-step guide
...
The system will begin booting a customized Tiny Core Linux live environment
Once the boot is complete, it will automatically launch the included script fsck-all (documented below)
The fsck-all script sleeps for eight seconds on start, both to allow time to exit if needed, and to allow for hardware devices to settle and be detected by the system
If fsck is not desired, as in you only want to run something else, or if it has completed and further test operations are desired, press Ctrl + C to exit the fsck-all script and get a system shell
If fsck has started scanning a drive, you must allow it to complete before Switchvox will boot properly again
Type the command ls - a lower-case 'LS' - to see a list of included scripts
...
fsck-all - automatically runs fsck on all the detected volumes in the system, after an eight second delay
File System Check - Runs 'e2fsck -yfcck' on each supported volume in the system
Only need to run if getting a request to manually run fsck when booting Switchvox, or as a way to run fsck in a maintenance window
When the fsck operation has completed, the script will prompt to press Enter to reboot or Ctrl + C to exit the test
NOTE: if fsck finds and corrects any errors, it is recommended to take backups, and reinstall at the earliest convenience
smart-all - automatically runs S.M.A.R.T. tests: short, conveyance, and long; on all the detected drives in the system
When the script has completed, it will prompt to press Enter to reboot or Ctrl + C to exit the test
check-smart-all - returns a status report from S.M.A.R.T. on all the detected drives in the system
shred-all - runs the shred utility on each drive in the system in turn, which will completely erase each drive
To run a different utility, merely type its name into the shell and press the Enter key to run it
smart-all and check-smart-all require no arguments to run, and can complete with no user intervention
shred-all will scan for existing drives in the system and present each one in turn for operation
It will display the drive letter, and a large warning informing that the contents of the drive will be erased
It will then require the user to fully type yes before it will begin the erase process on that drive
If a drive is having issues completing S.M.A.R.T. tests, but is not reported as FAILING, it is recommended to run shred-all on the drive
This will help force the drive to perform its regular sector re-map operation and can restore the proper functionality of the drive
...
MemTest86+ will launch and begin testing the system memory with no further user interaction
Watch until it indicates that the test has been completed
It should indicate whether there has been a Pass of the system memory, or errors will be displayed
