256  blocksize等于 Disk block size
257  secperblk等于blocksize右移9位
258  如果 Disk offset when reserved不等于0则

260  长字符串拼接
262  offset等于 Disk offset when reserved乘secperblk
263  size等于 Disk size in CMS blocks 减1的差乘secperblk
264  否则

266  长字符串拼接
274  如果labelsect恒等于1则offset等于2乘secperblk
276  否则offset等于labelsect加secperblk
278  size等于 Disk size in CMS blocks 乘secperblk
