General Limitations • CE boot partitions larger than 4000 megabytes are supported on some controllers. If your environment requires a CE boot partition larger than 4000 megabytes, consider the following: - Endurance Release 4.0 software does not provide extended INT13 BIOS support. Because of this, the size of the CE boot partition is restricted to sectors that can be accessed via INT13 calls that use Cylinder/Head/Sector (CHS) mapping. In CHS mapping, the maximum number of heads is 255; the maximum number of cylinders is 1023; and the maximum number of sectors per track is 63. Some controllers have lower limits than these, with the maximum sectors per track often being limited to 32, which creates a partition limit of 4000 megabytes. - The IOP SCSI/RAID controller to which the CE boot disk is attached is the component that determines the actual limit. If that controller supports 63 sectors per track by default, or can be configured to support 63 sectors per track for the CE boot disk, then you can have a partition size of 7.9 gigabytes. To use this partition size, configure both IOPs to support 63 sectors per track. For some controllers, you can choose between 2 gigabyte and 8 gigabyte support. Select 8 gigabyte support. • Network connections may be lost temporarily during CE resynchronization. To minimize the impact of such a loss, you can disable automatic synchronization. Then use a script to schedule CE synchronization at a convenient time. • After all steps in the CE Windows and Endurance Installation are complete, CE motherboard devices that were detected during unattended setup will appear in Device Manager with yellow warning circles. These devices have been disabled by the Endurance software. You can ignore the yellow warning circles. • The Endurance IOP installation procedure installs the IOP MIC driver programmatically rather than using the Add/Remove Hardware Wizard. A consequence of this is that the IOP MIC device appears in Device Manager under Other devices as a Mass Storage Controller with a yellow warning circle. You can ignore the yellow warning circle; there is nothing wrong with the MIC device. • The use of redirected floppy drives and redirected serial ports is not supported on Release 4.0. • Release 4.0 supports only PS/2 interfaces for the redirected keyboard and mouse. Redirected USB input devices are not supported. • CEs in Release 4.0 must be configured identically, including CPU cache and steppings.
