[問題]請問如何將ide的光碟機模擬成scsi

[necromancer]

小弟我最近在玩linux下的燒錄，查過資料--->xcdroast0.96之後，把ide的支援拿掉了，也就是說不管啥牌的cdrom，一律找不到，howto裡說要把ide模擬成scsi，這個地方我不太了解，有人可以說明一下嗎？

在 kernel config 裡的說明, 他是說要加 "hdx=scsi" 的 boot parameter, 其中 hdx 就是你想要模擬成 SCSI 磁碟的那台..... 不過要確定您的 kernel 有 enable "SCSI emulation supprt", "SCSI support", 以及 "SCSI generic support"
我自己沒有用過啦, 不過希望這些對您有幫助

[阿信]

可以在/etc/modules中加入ide-scsi的字串，

重開機就自動會將ide光碟機模擬成scsi

/dev/hda -> /dev/scd0
/dev/hdb -> /dev/scd1

以此類推。

[necromancer]

嗯， 還是找不到
我說明一下好了，我的燒錄器是scsi介面的，cdrom則是ide介面的
我用lilo開機，所以我在lilo.conf加入
append="hdc=ide-scsi"

在/etc/modules.conf加入

option ide-cd ignore='hdc'

在/etc/rc.d/rc.local加入
insmod ide-scsi

不知道有什麼錯，開機後，scsi-ide的mod也有載入
只是打cdrecord -scanbus
還是只有燒錄器一台而已

[阿信]

dmseg沒有寫出錯誤訊息嗎？

[necromancer]

沒有耶，這是我最感到奇怪的地方


我列出我的dmesg：

[阿信]

奇怪，沒看到ide-scsi的訊息呢，necromance兄用的是mdk阿，

我的debian只要modprobe ide-scsi就可以了，能否將/etc/modules中的ide-scsi順序寫到比scsi卡的上面。

[necromancer]

沒關係，信兄
我再去潛一陣子水
把原因找出來後再報告

研究中.....

[jesse.sung]

在/etc/rc.d/rc.local加入
insmod ide-scsi

請問您有載入 sg 和 sr_mod 嗎?
