Mainly compatibility issues, some motherboards may not run grub4dos, some may not load usbaspi

In earlier BIOS versions, the boot device boot sequence had only a few simple items such as C, A, CD-ROM, and now there are more than these in the BIOS, and it adds a lot of startup items. So, do you know what devices these startup items refer to? Floppy Soft disk drive, referred to as FDD, which is what we usually call the floppy drive. CD -ROMNeedless to say, we all know that this is a CD-ROM drive, that is, we usually speak of optical drive. SCSI The full name of the SCSI is: Small Computer
P3-P4:The problem is simple: the capacity of hard disk is increasing, 1TB has become the mainstream, however, data transmission speed has risen from the 1990 4.4mb/s only to the current 100mb/sReading a 1TB hard drive data takes at least 2.5 hours. Writing the data consumes more time. The workaround is to read from multiple hard drives, imagine that if there are currently 100 disks, each disk stores 1% data
, shock resistance is better than the traditional mechanical hard disk, in addition to read and write faster. Of course, the cost of flash memory is higher, so the price of SSDs is also higher. Take the same 1TB capacity for example, the traditional mechanical hard disk only about 500 yuan, while the SSD will need at least 2000 yuan.
