Troubleshooting
Problem:
The following warning appears in the Ultra100 TX2 BIOS: “[WA RNING] BECAUSE OF
40-CONDUCTOR CABLE(S) USED, Dx WOULD BE DOWN TO ULTRA33 MODE.
PLEASE USE 80-CONDUCTOR CABLE(S) IF ULTRA66 OR ABOVE MODE WANTED”.
Solution:
A 40-wire, 40-pin IDE cable is being used with an Ultra ATA/100 capable hard drive in
the Ultra100 TX2 hard drive setup. To access Ultra ATA/100 timing (and take
advantage of the full capabilities of your Ultra ATA/100 hard drive), you must use an
80-wire, 40-pin IDE cable. One 80-wire, 40-pin cable is included with the Ultra100 TX2
package. The colored edge of the cable(s) indicates pin 1 and the blue cable
connector must be attached to the Ultra100 TX2 connector.
Problem:
Determining hard drive performance.
Solution:
During the Ultra100 TX2 BIOS, the maximum transfer rate timing of the hard drive(s)
connected to the Ultra100 TX2 controller card will be displayed next to the model
name of the hard drive. Example: “D0 QUANTUM FIREBALL CR8.4A LBA 8056MB
ULTRA DMA 5.” “D0” identifies the master drive on the primary IDE port 1 on the
Ultra100 TX2 controller card (NOTE: if there is more than one device attached the next
device will be designated as D1, and so on); “QUANTUM FIREBALL CR8.4A”
represents the model name/number; “LBA” signifies that the drive size is being
translated so that the system can make use of the drive’s full capacity; “8056MB”
represents the drive’s capacity; “ULTRA DMA 5” identifies the maximum transfer rate.
Slower transfer rates include: “ULTRA DMA (0, 1, 2, 3, or 4)”; “DMA (0, 1, 2, or 3)”;
“PIO (0, 1, 2, 3, or 4).” To make full use of the performance enhancements of Ultra100
TX2, use only Ultra DMA 5 drives.
Problem:
FDISK reports a much lower drive capacity if a single drive exceeds 64GB.
Solution:
Due to a limitation with FDISK, the utility reports only the storage capacity that
exceeds 64GB. This is a cosmetic, not actual, limitation. Simply create a single DOS
drive partition, reboot, and then format the partition. The Format command will
recognize the total capacity of the partition accurately. Windows NT/2000/9x/ME will
now recognize the total capacity of your drive.
Problem:
While booting Windows NT4.0 or 2000 during a floppyless install, the message
“Inaccessible Boot Device” appears.
