In the displayed, formatted list of the current settings, numeric parameters are shown in decimal, except where otherwise noted.

To change a parameter setting, type:

---

setenv
 parameter value 

---

parameter is the name of the parameter. value is a numeric value or text string appropriate to the named parameter. A numeric value is typed as a decimal number, unless preceded by 0x, which is the qualifier for a hexadecimal number. Most parameter changes do not take effect until the next power cycle or system reset.

For example, to change the setting of the auto-boot? parameter from true to false, type:

---

ok setenv auto-boot? false
ok 

---

You can reset one or most of the parameters to the original defaults using the set-default parameter and set-defaults commands.

For example, to reset the auto-boot? parameter to its original default setting (true), type:

---

ok set-default auto-boot?
ok

---

To reset most parameters to their default settings, type:

---

ok set-defaults
ok
