Detailed Description
Preferred embodiments of the present invention are described in further detail below.
A method for improving the compatibility of a server to a hard disk comprises a hardware module part and a BIOS software part;
the hardware module part includes:
in hardware design, as shown in fig. 1, a SATA signal of a PCH is connected to a SATA slot, a GPIO on the PCH is connected to 5V and 12V power supply lines of the SATA slot, and then is pulled up to 5V and 12V power supplies through an external resistor, and whether the 5V and 12V power supplies of the SATA slot are supplied with power is controlled by controlling a high-low level of the GPIO, when the GPIO outputs a low level, the SATA slot is not powered on, and when the GPIO outputs a high level, the SATA slot normally supplies the 5V and 12V power supplies. Each GPIO corresponds to one SATA slot, and if the SATA slots are provided, the GPIOs are required to control the power supply condition of the SATA hard disk.
The BIOS software portion, as shown in fig. 2, takes the following steps:
step S1, after BIOS starts, firstly initializing GPIO, setting all GPIO for controlling SATA slot power supply to high level to make 5V and 12V power supply normally, then initializing SATA controller, allocating memory, IO and interrupt resource, opening all SATA Port functions, and making SATA controller and all hard disks connected on SATA Port create connection.
Step S2, after the SATA controller is initialized, the BIOS starts to process the SATA ports one by one, and first checks whether the device status bit of the SATA Port is set. Specifically, whether a device state bit of the SATAPort is set or not is checked by detecting the GPIO output state; when the GPIO outputs a high level, the device status bit of the SATA Port is set; when the GPIO outputs a low level, the device status bit of the SATA Port is not set.
If not, it indicates that the SATA Port is not connected to it, to prevent the hard disk from being connected abnormally, BIOS disables the SATA Port interface, waits for a delay and then turns on again, then checks again whether the device status bit is set, if not, BIOS considers that the SATA Port is not connected to the hard disk device or the hard disk device is bad, and checks the next SATA Port.
If the status bit of the SATA Port device is set to indicate that the hard disk device is connected, the BIOS checks the identification register, records the identification information sent from the register D2h for the first time, and determines whether the connection communication between the SATA controller and the hard disk is successful by checking whether the information in the identification register is valid.
When the identification information is invalid, the SATA Port is restarted quickly firstly, then the identification register is checked to see whether the identification information is valid or not, if the identification information is still invalid, the SATA Port is forbidden through the function register, a certain delay is waited, the SATAPort function is opened, then the identification information of the SATA Port is checked whether the identification information is valid or not, if the identification information is still invalid, the BIOS pulls down the SATAPort corresponding to the GPIO, the power supply of the SATA Port interface hard disk device is disconnected, after a certain delay, the GPIO is pulled up, the SATA Port interface hard disk is powered on again, the operation is equivalent to pulling out the SATA Port from the hard disk and then plugging in the SATA Port, the SATA controller and the hard disk device are reestablished, after a certain delay, the BIOS checks whether the identification register information of the SATA Port is valid or not, if the identification information is still invalid, the BIOS can repeat the restarting, the opening forbidding, the power-off and power-on operations for many times as required, eventually, it can be considered that the hard disk of the SATA Port interface may be out of service and needs to be replaced.
If the information of the identification register is valid, the SATA controller and the hard disk device are successfully connected and can normally communicate, and the hard disk can be normally used.
Step S3, BIOS judges whether all SATA ports have been checked, if not, it continues to check the next SATA Port, if so, it performs other operations to complete the connection check of the hard disk device.
In the above technical solution, the problem processing is performed in three levels, and the time consumption is gradually increased, so that the problem that can be processed by the first level is the best.
The invention relates to the technical term explanation of English abbreviation:
