二、光驱的安装方法 光驱是光盘存储器的简称,英文叫CD-ROM。CD-ROM是多媒体PC机的必备部件,它可以方便 地播放存储在其中的图像,CD-ROM盘容量相当大,当然CD-ROM并不仅仅用于DOS系统和Window s系统,它同样可以适用于UNIX系统,只要在UNIX系统下开发的应用系统,存放在CD-ROM盘上符 合UNIX系统允许的格式。CD-ROM盘与磁盘和软盘相比具有如下特点:
(1)CD-ROM盘一般是单面只读光盘,因为制造一张双面只读光盘的成本比两张单面只读光 盘要贵得多,所以目前市场上CD-ROM盘为单面5寸光盘。
(2)CD-ROM是大容量光盘存储器,CD-ROM可提供600MB以上的存储空间,现在市场上有650 MB、1.3GB、2.6GB等光盘,目前使用较多的为650MB光盘。CD-ROM读写时间比磁盘长,比软盘 要快得多,根据读写速度,市场上出现了二倍速、四倍速、六倍速、八倍速、十倍速、十二倍 速光驱。CD-ROM驱动器采用的是SCSI接口,要接在SCSI电缆上,SCSI电缆上可以接很多适用与 SCSI接口的设备。
现将光驱的安装方法介绍如下:
(1)引导系统进入维护状态,键入命令"#mkdev cdrom",并回车
(2)屏幕显示:
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:
键入1,并回车,屏幕显示:
The CD-ROM Drive must be Configured before use,Do you wish to configure the CD-ROM Drive now?(y/n)键入y,并回车,屏幕显示:
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:
回车默认的arad,arad为此机器的SCSI host adaptor的类型,不同的机器具有不同的类 型,如HP LC机为arad,而HP LH机、HP LS机为alad,键入h可知很多的类型,屏幕显示:
Which"arad"SCSI host adapter supports this device?
Select 0~2,or enter q to quit:
键入0,并回车,屏幕显示:
What is the Target ID for this device?
Select 0~7,or h for help or q to quit:
键入5,并回车,屏幕显示:
What is the LUN of this device?
Press<Return> to use the default:0Select 0~7,or h for help or q to quit:
键入0,并回车(注:键入的0、5、0三个数字为开机时系统默认显示的数字),屏幕显示参 数表:
Host AdapterType Device Adapter Number ID LUN
arad Stp 0 2 0
Update SCSI Configuration?(y/n)键入y,并回车,屏幕显示:
……The SCSI Configuration file has been updated. Do you want to configurat ion a CD-ROM/Tape installation device?(y/n)键入y,并回车,屏幕显示:

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:
键入1,并回车,屏幕显示:
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:
键入q,并回车,显示原来刚开始的信息,键入q,并回车,接着显示:
You must creat a new kernel to effect the change you specified.Do you wisht o creat a new kernel now?(y/n)键入y,并回车,下面提示新建的内核是否作为默认引导内 核,键入y,下面提示设置内核环境,键入y,重新启动即可。 |
