四个镜象文件放在D盘（FAT32) DOSUITLS 放在F盘里（FAT32,想把LINUX安装在此盘）
做一个虚拟软驱
重启以后用虚拟软驱引导进入DOS界面，调出AUTOBOOT后系统检测过程中屏慕显示了以后内容：
enabling IO-APIC IRQS
timer: vector = 0x31 pin1 = 0 pin2 = -1
mp-biosbug = 8254timer not connected to IO-APIC
tryint to set up timer(irqo) through the 8259A..failed
trying to set up timer as virtual wire IRQ...failed
tryint to set up timer as extint IRQ...failed :(.
kernel panic - not suncing:IO-APIC + timer doesn't work!boot with apic=debug and send a report.
then try booting with the 'noapic' option
