Unpacking Precautions

Some components on ROCKY-772EV SBC are very sensitive to
static electric charges and can be damaged by a sudden rush
of power. To protect it from unintended damage, be sure to
follow these precautions:
Ground yourself to remove any static charge before touching
your ROCKY-772EV SBC. You can do it by using a grounded
wrist strap at all times or by frequently touching any conducting
materials that is connected to the ground.
Handle your ROCKY-772EV SBC by its edges. Don't touch IC
chips, leads or circuitry if not necessary.
Do not plug any connector or jumper while the power is on.

2.4 Watch-Dog Timer (JP5)
Reading I/O port 443H enables the Watch-Dog Timer. It should
be triggered before the time-out period ends, otherwise it will
assume the program operation is abnormal and will issue a
reset signal to start again, or activate NMI to CPU. The Watch-
Dog Timer is disable by reading I/O port 043H or 843H. Refer to
Appendix A for detailed information on Watch-Dog Timer.

2.5 DiskOnChip™ Flash Disk
The DiskOnChip™ Flash Disk Chip(DOC) is produced by M-
Systems. Because the DOC is 100% software compatible to
hard disk and DOS, users don't need any extra software utility. It
is just "plug and play" easy and reliable. At present the DOC is
available from 2MB to 144MB. The DiskOnChip only shares
8KB memory address.
