unix安裝
光驅是光盤存儲器的簡稱,英文叫CD-ROM。CD-ROM是多媒體PC機的必備部件,它可以方便 地播放存儲在其中的圖像,CD-ROM盤容量相當大,當然CD-ROM並不僅僅用於DOS系統和Window s系統,它同樣可以適用於UNIX系統,只要在UNIX系統下開發的應用系統,存放在CD-ROM盤上符 合UNIX系統允許的格式。CD-ROM盤與磁盤和軟盤相比具有如下特點:
(1)CD-ROM盤一般是單面只讀光盤,因為制造一張雙面只讀光盤的成本比兩張單面只讀光 盤要貴得多,所以目前市場上CD-ROM盤為單面5寸光盤。
(2)CD-ROM是大容量光盤存儲器,CD-ROM可提供600MB以上的存儲空間,現在市場上有650 MB、1.3GB、2.6GB等光盤,目前使用較多的為650MB光盤。CD-ROM讀寫時間比磁盤長,比軟盤 要快得多,根據讀寫速度,市場上出現了二倍速、四倍速、六倍速、八倍速、十倍速、十二倍 速光驅。CD-ROM驅動器采用的是SCSI接口,要接在SCSI電纜上,SCSI電纜上可以接很多適用與 SCSI接口的設備。
現將光驅的安裝方法介紹如下:
(1)引導系統進入維護狀態,鍵入命令"#mkdev cdrom",並回車
(2)屏幕顯示:
CD-ROM Configuration Program
1.Install a CD-ROM Drive
2.Remove a CD-ROM Drive
3.Install a CD-ROM Drive
4.Remove a CD-ROM Drive
Select an option or enter q to quit:
鍵入1,並回車,屏幕顯示:
The CD-ROM Drive must be Configured before use,Do you wish to configure the CD-ROM Drive now?(y/n)鍵入y,並回車,屏幕顯示:
Enter the prefix of the SCSI host adapter that supports thisdevice or press ＜Return＞for the default:"arad"Enter h for a list of host adapters or enter q to quit:
回車默認的arad,arad為此機器的SCSI host adaptor的類型,不同的機器具有不同的類 型,如HP LC機為arad,而HP LH機、HP LS機為alad,鍵入h可知很多的類型,屏幕顯示:
Which"arad"SCSI host adapter supports this device?
Select 0～2,or enter q to quit:
鍵入0,並回車,屏幕顯示:
What is the Target ID for this device?
Select 0～7,or h for help or q to quit:
鍵入5,並回車,屏幕顯示:
What is the LUN of this device?
Press＜Return＞ to use the default:0Select 0～7,or h for help or q to quit:
鍵入0,並回車(注:鍵入的0、5、0三個數字為開機時系統默認顯示的數字),屏幕顯示參 數表:
Host AdapterType Device Adapter Number ID LUN
arad Stp 0 2 0
Update SCSI Configuration?(y/n)鍵入y,並回車,屏幕顯示:
……The SCSI Configuration file has been updated. Do you want to configurat ion a CD-ROM/Tape installation device?(y/n)鍵入y,並回車,屏幕顯示:
Configuring cdt driver..Updeating system configuration..System files have b een successfully updated.CD-ROM device unit 0(file CD-ROM device in /etc/conf/c f.d/mscsi)is configured as the CD-ROM/Tape installation device.Do you want to a dd/configure the high-sierra file system＞(y/n)鍵入y,並回車,屏幕顯示:
High Sierra/ISO 9660 filesystem configuration program
1.Add High Sierra/ISO9660 filesystem to system configuration
2.Remove High Sierra/ISO 9660 filesystem from system configuration
Select an option or enter q to quit:
鍵入1,並回車,屏幕顯示:
System configuration files have been successfully modified CD-ROM configura tion program.……Enter new string,"rm"to remove string,or enter q to leave curr ent string as is:
鍵入q,並回車,顯示原來剛開始的信息,鍵入q,並回車,接著顯示:
You must creat a new kernel to effect the change you specified.Do you wisht o creat a new kernel now?(y/n)鍵入y,並回車,下面提示新建的內核是否作為默認引導內 核,鍵入y,下面提示設置內核環境,鍵入y,重新啟動即可。
