SUMMARY

The Tentime SCSI host adapter TNT-4000 series uses a 8K address range in the Upper Memory Area (UMA). This adapter can be successfully used with Microsoft MS-DOS 5.0 or later. When using EMM386.EXE to load device drivers high, use the X= switch to exclude the range used by the SCSI host adapter. It is configurable for its interrupt and I/O address range usage and uses a device driver for its enhanced features.

MORE INFORMATION

The Tentime SCSI host adapter TNT-4000 series is configurable for several ranges, which are as follows:

O=On F=Off
Address       Jumpers
-------       14   15   16  17  18  19
C800           O    F    O   O   F   F      Default
D000           O    O    F   O   F   F
D800           O    F    F   O   F   F
E000           O    O    O   F   F   F
E800           O    F    O   F   F   F
To use EMM386.EXE to load device drivers high, be sure to exclude the range used by the SCSI host adapter. For example, if the card is jumpered for the default settings, exclude the address range by using the following device line in the CONFIG.SYS file.
   DEVICE=C:\DOS\EMM386.EXE NOEMS X=C800-C9FF
Other switches, including RAM, may still be used in conjunction with the X= switch.

The Tentime is also configurable for its interrupt and I/O address range usage. It can use the following:
     Interrupts
   3, 4, 5, 7, 10, 11, 12, 14, 15

   I/O address ports
   300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 3A0, 3B0, 3C0
The Tentime adapter also uses a device driver, SSTBIO.SYS, to take advantage of its enhanced features. This device driver is NOT essential to use the adapter. SSTBIO.SYS has been successfully loaded high using EMM386.EXE.
