Description of the update: This upgrade kit is suitable for U1-8K10 TV (40/58U1-8K10)
First, the local upgrade package download address
1.U1-8K10 no upgrade package
2. Factory package download address: http://pan.baidu.com/s/1sjyhH3v
Second, the update package local upgrade method Local upgrade method description:
Step 1: Before upgrading, be sure to unplug the SD card and disconnect all external devices from the TV (set-top box, Xbox, etc.)
The second step: download the address through the update package provided by the administrator, download the upgrade file (hereinafter referred to as the update package), and download the update package to the root directory of the U disk. (must be the root directory!)
Step 3: Plug the USB flash drive into the USB port on the TV back panel to enter the TV system settings - software update - local upgrade (Note: The local upgrade method for the software version V015.001.220 or later is: find the upgrade package through the "media player" , click Upgrade.)
Step 4: Confirm the version number you see in the local upgrade. It is the same as the downloaded local package number. Step 5: Click Upgrade. Do not power off or perform any operation during the upgrade.
Step Six: After the upgrade is successful, the TV will start automatically. Please restart the TV with power off.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
In addition to SCSI, IDE is also a very common interface. From the point of view of ease of use, IDE is more suitable for ordinary users. In addition, personal computer users not only need to configure a few peripherals, but also do not require high speed. Therefore, it is more appropriate to choose IDE interface. In addition, IDE also has the characteristics of high performance price ratio and wide application. Although the SCSI interface has many incomparable characteristics, the price of the interface and its peripherals is too expensive to be borne by ordinary users, which determines the limitation of its actual use range.
1. The working mode of IDE requires the whole process participation of CPU. When the CPU reads and writes data, it can't perform other operations. In this case, in the multitask operating system of Windows 95 / NT, the system reaction will be greatly slowed down. The SCSI interface controls the data reading and writing operation completely through the independent high-speed SCSI card, so the CPU does not have to waste time to wait, which obviously can improve the overall performance of the system. However, IDE interface has also made great improvements to improve this problem. DMA mode can be used instead of PIO mode to read and write data. DMA channel is responsible for data exchange, which greatly reduces the CPU consumption. However, comparing the CPU utilization of SCSI and IDE, we can find that SCSI still has considerable advantages.
2. The scalability of SCSI is larger than that of IDE. Generally, each ide system can have two IDE channels, with a total of four IDE devices. The SCSI interface can connect 7-15 devices, much more than IDE, and the cable connected is far longer than ide.
3. Although the price of SCSI device is higher, compared with IDE, the performance of SCSI is more stable, durable and reliable.
