Embodiment
Preferred embodiment of the present invention can be flash storage storage disks, or is a flash memory chip module.
Illustrate with flash storage storage disks earlier.With reference to figure 3, step 1 is a computer booting.After computer booting, enter step 2, starting BIOS.BIOS is check system and the Main Boot Record of BIOS is loaded in the random access memory in advance, and Main Boot Record comprises the data segment with school inspection information and has executable code segment.The configuration that executable code uses data message to come the compatibility and the system of verification hardware.After testing hardware compatibility and correct system configuration, executable code just loads the BIOS map among the RAM.The map of BIOS then enters the program of load operation system after ROM-BIOS.
So in step 4, judge at first whether the hard disk of computing machine can normal load operating system.If the hard disk of computing machine can normal load operating system, promptly enter step 4.1., by hard disk start-up function system.Otherwise, if the hard disk of computing machine can't normal load operating system, promptly enter step 5, further judge, whether can be by CD start-up function system.
If the CD of computing machine can normal load operating system, promptly enter step 5-1, by CD start-up function system.Otherwise, if the CD of computing machine can't normal load operating system, promptly enter step 6, by flash storage storage disks start-up function of the present invention system.
According to described implementation method of the present invention, when hard disk can't the start-up function system, no doubt can look for the CD that is loaded with operating system and come the start-up function system, but this practice bothers very much.If,, still can come the start-up function system by flash storage storage disks easily by the present invention so can't help the starting of hard disk or CD.Say nothing of and to have come the start-up function system by floppy disk again.
In addition, check in regular turn after the described start, also can be changed by the setting that BIOS is revised in the start back by hard disk, CD, flash storage storage disks, and the order of soft load operation system.
Thus, flash storage storage disks of the present invention just can replace the function of traditional floppy disk in the start-up function system fully.The former is described for another example, nowadays having hundred times of devices to floppy disk of multiple capacity on the market aspect storage data occurs, as with USB being storage card of interface etc., storage volume is all much larger than the storage volume of monolithic floppy disk, if therefore cooperate function of the present invention, just can needn't refill fully and establish floppy drive, both can reduce the cost of producing and assembling floppy drive, space and interface that simultaneously can also original floppy drive is shared be applied flexibly, can connect other such as CD-ROM, DVD-ROM, cd-recorder or the like periphery, strengthen the function that computing machine is brought into play.If do not want to install other periphery, then, also can make computer equipment compactification more by the space of the floppy drive that the present invention saved.
In addition, with reference to figure 4, flash of the present invention storage storage disks also can further dwindle into pattern with one chip (Single Chip) by the IC encapsulation technology, in other words, it is packaged into the pattern that a FDDI flash memory chip (162) is come the start-up function system.Thus, just FDDI flash storage storage chip (162) directly can be installed on the motherboard, replace the function of the start reparation operating system of traditional floppy drive by FDDI flash storage storage chip (162).Especially, because the volume of FDDI flash storage storage chip is little, and be directly to be contained on the computer main frame panel (170), so be particularly suitable for using in mobile computer.
