OEM Technical Manual • May 1999
3.5 Miscellaneous Information
Either the Sun keyboard and mouse or PS/2 keyboard and PS/2 mouse is supported
as the input device, and either TTYA or a video card is supported as the output
device. The determination of the input and output devices at power-up by the OBP
is shown in
TABLE 3-1.
There is adequate system level support to configure multiple video devices. At the
maximum, FFB2 plus 5 PCI graphics can be supported. If both FFB2 and PCI
graphics cards are used the system will default to FFB as console.
No system support is available to boot from floppy.
Volume Manager in Solaris has the capability of electrically ejecting removable
media. When using floppy drives, magnetic tape drives or CD-ROMs, the
appropriate eject commands should be used. The floppy drive is manual eject only.
Refer to the Solaris documentation.
Devices which participate in the Boot Process such as Boot Device, Standard IO,
must have OBP support.
The Ultra AXi motherboard has built-in OBP support for certain PCI graphics cards
from ATI. See Appendix E.
Use of Sun keyboards other than the Type 5 may result in unpredictable operation.
For example, the front power switch will not shut down the machine with a Sun
Type 4 keyboard attached.
