解决办法: 1、5.0.6a/5.0.7的源盘: 根据国外一些SCO论坛的帖子讲, SCO针对5.0.6a/5.0.7发布的"Wd Driver Supplement"补丁解决了这个问题, 在克隆前在源盘上使用custom安装这个补丁软件, 那么再克隆它应该能够解决克隆硬盘NO OS的问题, 即使硬盘几何参数不同,安装Wd补丁后引导模块也能按实际参数自动修正以正确引导。 看SCO的说法,该补丁提供下列新功能: * All compliant PCI IDE controllers now recognized. * UDMA mode 6 (UDMA 133) now supported. * Improved ATAPI device recognition. * ATAPI CD and DVD writer devices now supported. * More readable and useful debug output. To turn on debug output, use the wd.debug=[option] bootstring, where [option] can be any of the following: i for IDE controller identification u for Ultra DMA configuration g for disk geometry calculations * Better disk geometry configuration. * IDE hard disks larger than 137GB now recognized as having 137GB of space. Previously these drives were seen as smaller, possibly as small as 2GB. * When kernel debugger is enabled, driver no longer enters the debugger on certain unusual conditions. * Driver no longer panics when attempting to access a non-existent ATAPI device. 5.0.7的用户需要注意一点,如果你准备安装UpdatePack1, 那么需要先装UpdatePack1再装Wd Driver Supplement, Wd Driver Supplement的VOL安装包(用custom安装)下载地址: ftp://ftp.sco.com/pub/openserver5/drivers/OSR507/btld/wdsupp
