Device in computer system
View Patent ↗A device includes a PCH including a reset control pin and a disable control pin. A BIOS chip to control the PCH to send a low logic level from the reset control pin to the reset pin to reset a Ethernet controller. A timing adjusting circuit and the Ethernet controller. The Ethernet controller includes a reset pin and a disable pin, the reset pin is connected to the reset control pin via the timing adjusting circuit, and the disable pin is connected to the disable control pin via the timing adjusting circuit. The PCH sends a low logic level from the disable control pin to the disable pin to disable the Ethernet controller, and the timing adjusting circuit delays the low logic level, which makes the low logic level of the disable pin come later than the high logic level of the reset pin.
1. A device comprising:
a platform controller hub PCH comprising a reset control pin and a disable control pin;
a basic input/output system BIOS chip, connected to the PCH, to control the PCH to send a low logic level from the reset control pin to the reset pin to reset a Ethernet controller during booting of the device;
a timing adjusting circuit; and
the Ethernet controller, comprising a reset pin and a disable pin, the reset pin connected to the reset control pin via the timing adjusting circuit, and the disable pin connected to the disable control pin via the timing adjusting circuit;
wherein the PCH is further controlled to send a low logic level from the disable control pin to the disable pin to disable the Ethernet controller during booting of the device, and the timing adjusting circuit is configured to delay the low logic level, which makes the low logic level of the disable pin come later than the high logic level of the reset pin.
2. The device according to claim 1 , wherein the timing adjusting circuit is a programmable component.
3. The device according to claim 2 , wherein the timing adjusting circuit is a EPM3032ATC44-10N.
4. The device according to claim 1 , wherein the Ethernet controller is a 82599 chip.
