Video Card Conflict
- If using a different BIOS address (see Debug Hangs) does not solve the
problem, try turning the VGA memory access to 8 bit mode.
- Contact your vendor for technical assistance.
Slow in Formatting OR Every Sector is Reported as Bad During Verify
- Check to see that drive is set to hard sector mode.
- Check to see that the drive’s "sector per track" is set properly (Section
3.1.e).
Don’t Achieve Capacity Under DOS
Check to see if the correct mapping option is selected according to the drive
geometry and size. (See Appendix A, "Mapping Options for Drives Under Various
Operating Systems".) If incorrect mapping options are chosen (backup data from hard
disk, if necessary), delete all partitions that are already defined, then select and save
the correct mapping options in the Parameter Setup Menu. Using FDISK, redo the
drive partition and high level format.
Don’t Achieve Full Capacity Under OS/2 1.1, 1.2 for Drives Greater than
528MB
To obtain the maximum drive capacity (528MB) that OS/2 1.1, 1.2 can support,
select 63 sector mapping and 1024 Truncation mapping options for a drive that is
greater than 528MB. (See Appendix A, Mapping Options for Drives Under Various
Operating Systems, for other drive sizes.)
To achieve drive capacity above 528MB, please refer to Appendix F.
