BOOT FROM IDE2PCC
The IDE interface basically supports two different addressing modes: CHS (Cylinder, Head and Sector number)
according to the hard disk architecture (the hard disks which are normally installed to the IDE port are internally
organized in Cylinders Heads and Sectors) and LBA (Logical Block Addressing) which addresses the hard disk memory
in a linear way.
IDE devices (PC Cards in the IDE2PCC are working in true IDE mode) are in general not for use in different computer
systems. Because the several BIOS’ have an other translation of the CHS numbers. There is no guarantee that a PC
Card formatted and installed in a laptop or an other PC-System also can be used in e.g. a PIP6 (or also a third computer
system). That is a systematic PC architecture problem.
The best way for avoiding troubles with booting: Low level format (erase the Boot Sector) the needed PC Card, format it
and make the installation of the operating system in the computer system that is intended to boot from this PC Card (just
the way you do it with a new fix installed hard-drive).
The other possibility is if you don’t want to install the PC Card on the end system, you must insure that the computer
system you take for installing the PC Card and the computer system you take to use the PC Card have a BIOS that use
the same IDE addressing (you reach the best results by using LBA mode).
