1747-UM001A-US-P - March 2000
4-8 Starting the Open Controller
Considerations
Considerations of this configuration include:
•
This method only works for some operating systems, such as DOS or
Windows 3.x. Operating systems with built-in card and socket services,
such as Windows 95 and Windows NT, will not boot using this method.
•
Card and socket services software (such as CardSoft) cannot be loaded
because it breaks the BIOS connection to the PCMCIA interface module.
This means that you cannot use the second PC Card slot in the PCMCIA
interface module.
Important: If you want to boot from an ATA PC Card and use other PC
Cards at the same time, place the ATA PC Card in an
1747-OCIDE1 IDE interface module. The ATA PC Card must
be IDE compatible. Then you can load card and socket services
software and use other PC Cards in the PCMCIA interface
module.
•
The ATA memory device will not appear as an IDE drive, so
functionality and performance will differ from that of native IDE drives.
Only use this method temporarily to load an operating system or other
software on the native IDE drive.
Steps
1. Insert a bootable ATA memory device into the open controller:
2. Change BIOS settings.Table 4.F shows the required BIOS settings,
assuming that you are using an internal (embedded) FlashDrive,
CompactFlash, or microdrive. The BIOS settings not shown don’t affect
booting from a PCMCIA interface module. See chapter 3 for additional
BIOS information.
If you are using: Then:
1747-OCE insert the ATA device in the LEFT slot (slot 0) of the RIGHTMOST
1747-OCPCM1 interface module in the open controller chassis.
1747-OCF insert the ATA device into the RIGHT slot (slot 1) of the LEFTMOST
1747-OCPCM1 interface module in the open controller chassis.
