In this user guide, we describe some of the possible causes that might cause the Solaris Sparc Set to create a bootable floppy disk, and then suggest some possible solutions that you can use to try to resolve the issue.
The following information describes the different ways to view andSet shoe attributes on SPARC and x86 platforms. For specific setup informationBoot attributes for x86-based systems, or during additional boot with bootadm command, see x86: Adding Kernel Arguments by Editing the GRUB Menu at Boot.
Fortect is the world's most popular and effective PC repair tool. It is trusted by millions of people to keep their systems running fast, smooth, and error-free. With its simple user interface and powerful scanning engine, Fortect quickly finds and fixes a broad range of Windows problems - from system instability and security issues to memory management and performance bottlenecks.
1. Download Fortect and install it on your computer

SPARC: View And Set Boot Attributes Using OpenBoot PROM
Boot PROM is used to boot a SPARC based system andConfigure launch options. For example, you might consider factory resetting your device.which should be skipped, boot, standard boot file, or possibly kernel, or startupHardware diagnostics before the application enters a multi-user state.
If you need to do any of the following, you will need someoneto change the default startup of one device:
Absolutely or temporarily add a new disk to the system
Change Network Launch Policy
Temporarily build a network independent system
For a complete list of PROM commands, see Monitor (1M) and eeprom (1M).manual pages.

SPARC: How To Identify Devices In The System
You may need to specify which devices the system can successfully identifyappropriate download devices.
Before buyers can safely use probe commands to determine what kind of device they areattached to a circle, you need to do the following:
Change PROM value autoload? to false .Setenv
autoloading ok? false
Run the reset-all command to clear the policy registers.
OK, reset everything
You can view the exam requirements available for your arrangement whileusing the command sieve probe :
ok sieve probe
If someone runs probe commands without clearing registers, do the following:Message displayed:
ok, probe-scsiThese instructions can block the system when using reasonable commands Stop-A or Halt.was completed. Please reset everything to reset the processbefore running this command. Youdo you ask to continue? (yes / no) no
Identify devices on the system.
ok probe- device
(Optional) Whether to restart the whole body after the current crash orafter someone used the reset command and then reset a certain auto-boot value? to true .
good, setenv truestart automatically? start automatically? means true
Boot the system in multiuser mode.
OK reset-all
The following example shows how the devices connected to the system are identified.

Wrongstart automatically? = falseok drop everythingSC warning: host system rebootedSun Fire T200, no keyboard.........Ethernet host address 0: 14: 4f: 1d: e8: da, ID: 841de8da.ok probe idea Device 0 (mainth master) Detachable ATAPI Model: MATSHITACD-RW CW-8124 Device 12 (master slave) Not here Device 2 (secondary master) Not here Third device (secondary slave) Not hereok, setenv autoload? truthstart automatically? = true
You can also use the devalias directive to define a device alias andrelated device paths that may be relevant to the system.For example:
Specifies the true value of the device parameter to boot.
For more information, see the printenv (1B) paper man.
The default is Boot Device , which is displayed in a format similar to the one usedNext:
Boot device is / pci @ 7c0 / pci @ 0 / pci @ 1 / pci @ 0.2 / LSILogic, sas @ 2 / disk @ 0.0: a
If boot-device specifies a network boot device, the output is often the sameto the following:
boot-device = / sbus @ 1f, 0 / SUNW, fas @ e, 8800000 / sd @ a, 0: a n/ sbus @ 1f, 0 / SUNW, fas @ e, 8800000 / sd @ 0,0: storage network
SPARC: How To Change The Default Boot Device Using Boot PROM
You may need to identify devices in practice before usemay change the starting decision It is not the default to another device. For more information on identificationPeripherals in the system, see SPARC: How to identify devices in the system.
Become a kind of root role.Specify an alternate device General to start. # eeprom boot-device new-boot-device.Check who, in turn, created the new launch parameter. # eeprom boot device. The output should filter out the new eeprom value to customize the person’s boot device.
In a typical production environment, you need to ensure that the hard drive of the root operating system is mirrored. You can avoid separate sources of error.ok> printenv boot-device boot-device = rootdisk mirrordisk.
Become a superuser.Stop the system created with init (1M).When you see this> PROM prompt, also type n to hit Enter.Change the settingboot device using the setenv command.Test switching to the default boot device using our own printenv command.
