This call is enhanced to report the processor core speed and the maximum number of processors in the system. The way
processors are numbered is also changed.
7.3.5 Boot Options
The SRMK2 BIOS conforms to the BIOS Boot Specification (BBS). There are several additional
BIOS features not described in the BBS, which pertain to booting. These are described in the
following sections.
7.3.5.1
Quiet Boot
The BIOS includes a default Intel logo that can optionally be displayed during BIOS POST in lieu
of the POST diagnostic screen. If the Quiet Boot feature is disabled via BIOS setup, during
POST the BIOS displays the usual POST screen including the memory count and processor
information. If Quiet Boot is enabled and a valid logo is detected, the BIOS displays the logo
during POST and suppresses the usual POST screen. The user may press the
switch to the POST diagnostic screen from the logo. The BIOS erases the logo when option
ROMs are scanned, because some option ROMs expect the video to be in text mode. The OEM
splash screen implementation follows the guidelines specified in PC99 System Design Guide. See
Section 14.2 for information about this specification. While the splash logo is displayed, the video
is in graphics mode. The BIOS logo can be customized, see Section 7.3.6 for detail.
7.3.5.2
PXE Boot
The SRMK2 BIOS provides network boot support as described in the Preboot Execution
Environment (PXE) Specification, ver 1.0 and the Preboot Execution Environment BIOS
Support Specification, ver 1.1. This feature works within the standard framework of the BBS
support. See Section 14.2 for information about this specification.
