7.4 Installation & Runtime Problems
This segment covers certain problems which may be encountered during
SuperTrak66 installation, configuration and run-time.
Event: SuperTrak66 BIOS does not show up
Cause: Being fully PnP compatible, the SuperTrak66 controller card offers no
means of overriding the assigned memory address at which the BIOS will
appear. It is entirely dependent upon the system BIOS being able to
properly allocate a memory address resource for it. Make sure that your
system PnP/PCI configuration allows for the BIOS to have a memory
address between 640K and 1MB (more specifically, anywhere from
0xC8000 to 0xE8000, a total of 64KB). If your system BIOS supports ROM
shadowing, you can disable ROM shadowing for a particular address at
which the SuperTrak66 BIOS will then load.
Event: No LEDs on card light up
Cause: The SuperTrak66 card is not connecting with the computer. Make sure the
card is fully seated in the PCI slot and that the data cable ground straps
are properly secured.
Message: "NO ROM BASIC, SYSTEM HALTED"
Cause: This message is displayed when trying to boot a system from a
drive which has no “active” partition on it. Use FDISK or a similar
utility to set the active partition.
Event: Thermal recalibration interrupts sustained transfers
Cause: Thermal recalibration on older drives takes from 3 to 5 seconds depending
on the drive. Newer drives have much better algorithms for thermal
recalibration that last no longer than half a second. During this time, drive
I/O may be buffered by the SuperTrak66 cache. Replacing older, slow
recalibration drives with newer, faster models should be sufficient to
sustain uninterrupted data transfers.
