關於硬碟的"geometry - BBS

想請教一下
我的主機板是比較舊的
接了三個硬碟 分別是 hitachi 120g maxter 120g hitache 160g
簡稱(H120, M120, H160)
開機的時候
BIOS分別抓到
H120 : 116G
M120 : 116G
H160 : 137G

我以前是用Freebsd 4.7來fdisk他的 沒下什麼特別參數 就整個硬碟切一個區
/dev/ad1s1e 113G 99G 5.0G 95% /mnt/hitachi
/dev/ad2s1e 113G 92G 12G 89% /mnt/maxtor
/dev/ad3s1e 151G 130G 8.9G 94% /mnt/hitachi160
分別抓到的

之後 換到Freebsd 5.3的機器上

在/stand/sysinstall底下 這三顆硬碟會顯示
H120:
WARNING: A geometry of 239340/16/63 for ad1 is incorrect. Using │
│a more likely geometry. If this geometry is incorrect or you │
│are unsure as to whether or not it's correct, please consult │
│the Hardware Guide in the Docume ntation submenu or use the │
│(G)eometry command to change it now. │

│Remember: you need to enter what ever your BIOS thinks the │

M120:
WARNING: A geometry of 238216/16/63 for ad2 is incorrect. Using
H160:
WARNING: A geometry of 319120/16/63 for ad3 is incorrect. Using │

差別只在第一行

請問 這種情況 該到BIOS去自己手動調整嗎?

謝謝
