5. The Wisdom 1
All is created twice:
In Mind
In Reality
Study Build
Nothing Plan Reality
Create Work
Innovate Tell
To help you “Plan”
What is Logaritm for ?
What is Math for ?
What is Fourier Transform for ?
6. The Wisdom 2
At t=0 S is closed
V(t) = i(t).(R+r)
S
Vc(t) = 1/C ∫ i(dt)
E C R, r
V
i(t)
E
If this is “the plan”
What is the reality ? t
0
7. The Wisdom 3
Learn from the Human Body
(God, the Maha Guru, speaks not only from The Bible, the Revelation or enlightment)
CREATURE lives in its NATURE = space & time
Space: 1D, 2D, 3D, 4D etc..
Time: chronological, freeze, in the past, in the future, balanced, omnipotence
The composition makes the “character”

26. Changing role of the BIOS
Some operating systems, for example MS-DOS, rely on the BIOS to carry out most input/output
tasks within the PC.[9]
Larger, more powerful, servers and workstations using PowerPC or SPARC CPUs by several
manufacturers developed a platform-independent Open Firmware (IEEE-1275), based on
the Forth programming language. It is included with Sun's SPARC computers, IBM's RS/6000
line, and other PowerPC CHRP motherboards.
Later x86-based personal computer operating systems, like Windows NT, use their own, native drivers
which also makes it much easier to extend support to new hardware, while the BIOS still relies
on a legacy 16-bit real mode runtime interface.
There was a similar transition for the Apple Macintosh, where the system software originally relied
heavily on the ToolBox—a set of drivers and other useful routines stored in ROM based on
Motorola's 680x0 CPUs. These Apple ROMs were replaced by Open Firmware in the PowerPC
Macintosh, then EFI in Intel Macintosh computers.
Later BIOS took on more complex functions, by way of interfaces such as ACPI; these functions
include:
• power management,
• hot swapping,
• thermal management.
Extensible Firmware Interface (EFI) is a specification which replaces the runtime interface of
the legacy BIOS. Initially written for the Itanium architecture, EFI is now available for x86
and x86-64 platforms; the specification development is driven by The Unified EFI Forum, an
industry Special Interest Group.
Linux has supported EFI via the elilo boot loader. The Open Source community increased their
effort to develop a replacement for proprietary BIOSes and their future incarnations with an
open sourced counterpart through the coreboot and OpenBIOS/Open Firmware projects.
AMD provided product specifications for some chipsets, and Google is sponsoring the project.
Motherboard manufacturer Tyan offers coreboot next to the standard BIOS with their
Opteron line of motherboards. MSI and Gigabyte Technology have followed suit with the MSI
K9ND MS-9282 and MSI K9SD MS-9185 resp. the M57SLI-S4 models.
Some BIOSes contain a "SLIC", a digital signature placed inside the BIOS by the manufacturer,
for example Dell. This SLIC is inserted in the ACPI table and contains no active code.
Computer manufacturers that distribute OEM versions of Microsoft Windows and Microsoft
application software can use the SLIC to authenticate licensing to the OEM Windows
Installation disk and/or system recovery disc containing Windows software.
Recent Intel processors (P6 and P7) have reprogrammable microcode. The BIOS may contain
patches to the processor code to allow errors in the initial processor code to be fixed,
updating the processor microcode each time the system is powered up. Otherwise, an
expensive processor swap would be required.[10] For example, the Pentium FDIV bug became
an expensive fiasco for Intel that required a product recall because the original Pentium did
not have patchable microcode.
