回复 #2 sratlf 的帖子
这是另一台机器,求大家讲解:
主板 梅捷sy-i6h-L v2.0
2g内存
集显256m
grub4dos 0.4.5c 2012-02-27 638k/511m/6m end:354610
我做的img是510m的,奇怪的是 map --mem 就会重启,map --mem --top竟然成功了
是不是因为grub4dos 用的高位内存 是高位内存中最靠后的区间,而很幸运地,最后一段连续空间也大于510m?
displaymem结果:
eisa memory bios interface is present
address map bios interface is present
lower memory:635k,upper memory(to first chipset hole):523264k
[address range descripter entries immediately follow(values are 64-bit)]
