2.
No BIOS message from DC-820B appears on the screen:
n
ROM address conflicting with other I/O card(s) -> check the ROM
addresses of all the I/O cards and make sure none are conflicting
n
VGA card with “Fast Address Decode” option enabled -> this may
cause all I/O cards that employ 8-bit ROM BIOS, DC-820B in-
cluded, not to be recognized. Please disable this option, if possible.
3. Missing operating system (normally happens in drives previously used
with other adapters):
n
Under BIOS (INT 13H) -> please refer to guideline 1. If correct, then
go on to perform partitioning by using the DOS FDISK command
4.
FDC error:
n
Could be more than one FDC enabled -> make sure only one FDC is
enabled
5.
Devices not recognized:
n
Check if the cabling and terminators are properly installed
n
Some specific drives, such as Hitachi's, need more power-on delay
time. Try to set the Power ON Delay for SCSI Devices option to a
longer dealy.
6.
Cannot access your adapter when executing the ECU:
n
Could be installed in a slot not supporting the bus master -> refer to
the mainboard menu and install your adapter into a bus-master sup-
porting slot
7. Possible incompatibility problems when enabling the DOS 5 support
option in ECU:
n
Due to the condition of occupying the 1KB (639KB-640KB) memory
space, some software programs, such as virus-protection programs,
may issue false alarms.
8. Surprisingly fast "FORMAT" means not completed ?:
n
The "FORMAT" is actually done. Due to that the time-consuming
command (READ VERIFY) is ignored to improve the performance,
your drive will respond to the FORMAT command very quickly.
