标题: 急向各位大神求助！！
　　本人用的DELL O755的电脑，最初是1G 内存，后来为了玩RAMOS，断断续续加到了现在的8G内存。XP下显示可用内存为3G，装了Primo Ramdisk并开启不可见内存支持后认出了5052M的高位内存。

　　但是这5052M内存却被奇怪地分成了两部分（大概4032M、960M），所以一直无法使用超4032M的RAMOS XP系统。

　　所以一直浪费了4032Ｍ以外的高位内存，因为即使用Primo Ramdisk能认出所有的高位内存，但如果要使用肯定会跟Firadisk使用的高位内存冲突（我已经试过：启动时蓝屏），因为Primo Ramdisk没有避开Firadisk使用的那部分内存。

　　偶然一次看到Primo Ramdisk网站说明在使用不可见内存时有个选项：保留不可见内存的前边xxxM部分不用，这又让我有了希望。

　　我的问题是：我如何才能知道我用grub4dos所map的firadisk内存盘占用了哪部分内存，从而让Primo Ramdisk避开？

　　以下是我从grub4dos启动时导出的内存情况：
