DTCIDE.ADD
Syntax
BASEDEV=DTCIDE.ADD <parameters>
Parameters
- /V
- Verbose Mode
- Displays controller status, drive geometry information, drive name and the drive mode during OS/2 initialization. This is a global switch and can be placed anywhere after DTCIDE.ADD.
- /2
- 2 Adapters
- If there two adapters, this switch is required. All switch settings, except the global switches, before this switch are designated to the first (or primary) adapter and those after this switch are designated to the second (or secondary) adapter.
- /Dx
- /D0:MX = Block size of the master drive
- /D1:MX = Block size of the slave drive
- Where X is the number of blocks of the multi-sector transfer mode. The optimal value for the best performance is 8. Many of the drives on the market support up to 8 sector per block. The value of 0 or 1 sector per block will cause the block mode to be disabled.
- /D0:PX = PIO Data Transfer Mode of the master drive
- /D1:PX = PIO Data Transfer Mode of the slave drive
- Where X is from 0 to 3, the value of the transfer mode. This switch setting is applicable only to DTC2130. The speed translation is as follows:
| PIO MODE | Transfer Speed |
|---|---|
| 0 | 3.3 MBytes/Sec |
| 1 | 5.22 MBytes/Sec |
| 2 | 8.33 MBytes/Sec |
| 3 | 11.1 MBytes/Sec |
- /D0:LX = LBA Mode Enable/Disable for the master drive
- /D1:LX = LBA Mode Enable/Disable for the slave drive
- If the drive supports LBA mode, it is turned on automatically. The user can turn it off by specifying "L0" for that drive. If the drive does not support LBA mode, specifying "L1" will be ignored.
- /2130S
- Make 2130 as Secondary
- This switch will work only for some motherboards with IRQ15 connected to the specific PCI slot where DTC2130 is located. This is a global switch.
Examples
BASEDEV = DTCIDE.ADD /2130S /D0:M8 /D1:P1 /2 /D0:L0 /D1:P0
This statement load the DTCIDE.ADD driver with two DTC IDE controllers, of which, the secondary controller is DTC2130. Of the primary controller, the block size of the master is 8 sectors per block and the PIO speed mode of the slave drive is 1. On the secondary controller, which is 2130, the LBA mode of the master drive is disabled and the PIO speed mode of the slave drive is 0.
