System does not boot during installation

If the system does not display prompts for starting the installation the first time you boot from the Boot Disk:

1. Verify that the Boot Disk is in the drive. If another floppy disk is in the drive, the system does not display the Boot: prompt. Replace the floppy disk with the Boot Disk and reboot the machine.

2. If the Boot Disk is in the drive and the machine still does not boot, make sure that the floppy disk is inserted correctly and that the floppy disk drive door is closed. Then, reboot the machine.

3. If the Boot Disk still does not boot, verify that your floppy disk drive works by booting a DOS disk.

4. If the floppy disk drive works, your problem may be a damaged Boot Disk. Verify the media by booting on another similar machine if possible. If the Boot Disk is damaged and you do not have a backup copy, request a new Boot Disk from your software provider.

1. Check that your system has enough RAM (Random Access Memory) -- see your computer's documentation. Your computer must have the minimum recognized memory (see ``Basic hardware requirements'') to install the operating system.

   At the Boot: prompt, entering the command mem=/p displays all the RAM the system will use. On most systems, you can override this default using the mem= command. See the boot(HW) manual page.

2. If your system has enough RAM, check that the boards (bus cards) are seated properly.

3. If the system still does not boot, you may have a badly configured floppy disk drive. Make sure that the values in the CMOS match the drives actually attached to the system and that the positions of multiple drives on the drive cable match the BIOS configuration. If the CMOS setup has a Swap drives setting, make sure this is turned off.

4. Check that all cards are supported (see the SCO Certified and Compatible Hardware web page for a list of supported disk drives) and correctly configured (as described in ``Basic hardware configuration'').

5. Disable cache (to enable diagnostics) and shadow RAM.

6. If, after performing all the above tests, the system still does not boot, you may have a hardware failure. Check the documentation that came with your computer for hardware tests.
