13 .fi
15 .SH DESCRIPTION
16 .LP
17 \fBeeprom\fR displays or changes the values of parameters in the \fBEEPROM.\fR
18 It processes parameters in the order given. When processing a \fIparameter\fR
19 accompanied by a \fIvalue\fR, \fBeeprom\fR makes the indicated alteration to
20 the \fBEEPROM;\fR otherwise, it displays the \fIparameter\fR's value. When
21 given no parameter specifiers, \fBeeprom\fR displays the values of all
22 \fBEEPROM\fR parameters. A `\|\(mi\fB\&'\fR (hyphen) flag specifies that
23 parameters and values are to be read from the standard input (one
24 \fIparameter\fR or \fIparameter\fR\fB=\fR\fIvalue\fR per line).
25 .sp
26 .LP
27 Only the super-user may alter the \fBEEPROM\fR contents.
28 .sp
29 .LP
30 \fBeeprom\fR verifies the \fBEEPROM\fR checksums and complains if they are
31 incorrect.
32 .sp
33 .LP
34 \fIplatform-name\fR is the name of the platform implementation and can be found
35 using the \fB-i\fR option of \fBuname\fR(1).
36 .SS "SPARC"
37 .LP
38 \fBSPARC\fR based systems implement firmware password protection with
39 \fBeeprom\fR, using the \fBsecurity-mode\fR, \fBsecurity-password\fR and
40 \fBsecurity-#badlogins\fR properties.
41 .SS "x86"
42 .LP
43 \fBEEPROM\fR storage is simulated using a file residing in the
44 platform-specific boot area. The \fB/boot/solaris/bootenv.rc\fR file simulates
45 \fBEEPROM\fR storage.
46 .sp
47 .LP
48 Because x86 based systems typically implement password protection in the system
49 \fBBIOS,\fR there is no support for password protection in the \fBeeprom\fR
50 program. While it is possible to set the \fBsecurity-mode\fR,
51 \fBsecurity-password\fR and \fBsecurity-#badlogins\fR properties on x86 based
52 systems, these properties have no special meaning or behavior on x86 based
53 systems.

70 .sp .6
71 .RS 4n
72 A configuration variable that controls the use of Advanced Configuration and
73 Power Interface (ACPI), a power management specification. The acceptable values
74 for this variable depend on the release of the Solaris operating system you are
75 using.
76 .sp
77 For all releases of Solaris 10 and Solaris 11, a value of of \fB0x0\fR means
78 that there will be an attempt to use ACPI if it is available on the system. A
79 value of \fB0x2\fR disables the use of ACPI.
80 .sp
81 For the Solaris 10 1/06 release, a value of \fB0x8\fR means that there will be
82 an attempt to use ACPI in a mode compatible with previous releases of Solaris
83 10 if it is available on the system. The default for Solaris 10 1/06 is
84 \fB0x8\fR.
85 .sp
86 For releases of Solaris 10 after the 1/06 release and for Solaris 11, the
87 default is \fB0x0\fR.
88 .sp
89 Most users can safely accept the default value, which enables ACPI if
90 available. If issues related to the use of ACPI are suspected on releases of
91 Solaris after Solaris 1/06, it is suggested to first try a value of \fB0x8\fR
92 and then, if you do not obtain satisfactory results, \fB0x02\fR.

102 Specifies the console device.
103 Possible values are \fBttya\fR, \fBttyb\fR, \fBttyc\fR, \fBttyd\fR, and
104 \fBtext\fR. In \fBtext\fR mode, console output goes to the frame buffer and
105 input comes from the keyboard. For SPARC, when this property is not present,
106 the console device falls back to the device specified by \fBinput-device\fR and
107 \fBoutput-device\fR. When neither the console property or the
108 \fBinput-device\fR and \fBoutput-device\fR property pair are present, the
109 console defaults to the frame buffer and keyboard.

130 The \fBdiag-device\fR is currently implemented to support serial port
131 as output for system early boot diagnostic messages and input and output
132 for \fBkmdb\fR debugger. For early boot, all the console messages are mirrored
133 to \fBdiag-device\fR, until the console drivers are loaded.
134 After that, only \fBkmdb\fR will continue to use the \fBdiag-device\fR.
