sunv20,无法正确识别随机硬盘容量,需要安装sun提供patch,始终无法按sun doc操作,doc原文:
"OS Installation from CD-ROM with ITU Floppy Diskette
----------------------------------------------------
Here are the steps to use drivers on the Solaris Driver ITU diskette
to install Solaris (Intel Platform Edition) on a machine with new hardware.

To install the ITU while installing the Solaris 10 OS from CD-ROM:

1. Power on your machine.
2. Insert Installation Disc 1 of your Solaris 10 OS.
    The first screen is the Solaris Device Configuration Assistant.
3. Press ESC to interrupt autoboot.
4. Insert the ITU floppy diskette.
5. Press <F4> to add a device driver.
    The Bus Enumeration screen appears. The system determines the types of
    bus and gathers hardware-configuration information.
6. Press ENTER to continue.
    Note - This key may be labeled as RETURN on your keyboard.
    The Install Supplemental Drivers screen appears.

总是出现grub引导画面,不能执行3-5步,如何克服? os:solaris10u1

另安装时可选ftp安装,不知ftp server端需放什么文件内容,sun下载的jun为iso.zip.

10u1已经用grub代替Solaris Device Configuration Assistant,怎么操作?
ftp安装只能装Solaris Flash文件,有没有现成v20模板文件下载?
