Does anyone have experience with changing the BIOS-CMOS?
My problem: I want to run an HMG program EVERY day at 6 AM for example.
Since my PC is turned off, the BIOS must be adjusted so that it starts up at 6:00 AM,
and start my program. My program also provides the shutdown when it notices
that it started between 05:50 and 06:10.
I have adjusted my CMOS Setup (resume by .. everyday.. etc.) , saved, and after that everything went well only one time (the first time).
Now it doesn't seem to work at all.
Can I check my CMOS-BIOS in order to see if my changes are set (instead of interrupting startup with F10)?
Or somebody has an idea has is going wrong?
Thx, Serge
hello Serge,
shutting down the computer would be no problem you can use windows command to do this vi shellexecute in your application = shutdown / m \\ 192.168.56.1 -s -f -t 0.
To connect you can use your computer's network card and a Wolcmd utility from another computer or server:
1 - wake on lan power management network properties
2 enable bios may have several names for this option depending on your motherboard
a-power on by pci
wake up on lan
c- by boot = boot generation - pci dev
wolcmd commands:
Wolcmd MAC MASK IP_MACHINE PORT (Example: Wolcmd 3423877584C1 192.168.56.1 255.255.255.0 7)
we can try to develop something with hmg because it uses brodcast protocol to send the package follows some references:

SOURCE ADDRESS, DESTINATION ADDRESS
(which may be the receiving station’s IEEE address or
a MULTICAST address which includes the BROADCAST address), and CRC.The specific sequence consists of 16 duplications of the IEEE address of this
node, with no breaks or interruptions.
This sequence can be located anywhere within the
packet, but must be preceded by a synchronization
stream. The synchronization stream allows the scanning state machine to be much simpler.The synchronization stream is defined as 6 bytes of FFh. The device
will also accept a MULTICAST frame, as long as the 16
duplications of the IEEE address match the address of
the machine to be awakened.
If the IEEE address for a particular node on the network
was 11h 22h 33h 44h 55h 66h, then the LAN controller
would be scanning for the data sequence (assuming an
Ethernet Frame):
