SBTSR.EXE
SBTSR.EXE is a DOS terminate-and-stay-resident (TSR) utility used to configure and enable the PicoPCMCIA Card.
The program configures a PCMCIA socket through an Intel-compatible PCIC controller and exposes Sound Blaster compatible resources to DOS software.

Known Limitations
- Currently only works with Intel-compatible PCIC controllers.
- The program cannot automatically detect the controller or socket.
- The user must manually specify the PCIC controller and socket using command-line arguments.
- Several hardware resources are currently hardcoded in this version.
Usage
Arguments are specified as a letter immediately followed by a value. Arguments are separated by spaces.
Example:
SBTSR.EXE c1 s1
This specifies:
- PCIC Controller 1
- PCIC Socket 1
Arguments may appear in any order.
Valid examples:
SBTSR.EXE c1 s0 SBTSR.EXE s0 c1
Invalid usage:
SBTSR.EXE c 1 s 0
Command Line Arguments
| Option | Description | Allowed Values | Default |
|---|---|---|---|
| c | PCIC controller number | 0–3 | 0 |
| s | PCIC socket number | 0–3 | 0 |
| i | Virtual IRQ used by the Sound Blaster interface | Any valid IRQ | 5 |
| h | Hardware IRQ used by the card | 8–15 | 10 |
| n | Memory window segment used by the card | Hex segment value | D000 |
Hardware Resources
In this version several resources are currently hardcoded.
I/O Windows
| Window | Address Range |
|---|---|
| I/O Window 0 | 0x240 – 0x256 |
| I/O Window 1 | 0x300 – 0x3FF |
Virtual Interrupts
| Device | Virtual IRQ |
|---|---|
| COM1 | 4 |
| NE2000 | 3 |
| Sound Blaster | Configurable (default 5) |
Operation
When executed, the program performs the following sequence:
- Configures the specified PCIC controller and socket.
- Enables the card.
- Waits for the device to become ready by polling a value in the configured memory window.
If the expected value is detected, the TSR installs and remains resident.
If the value is not detected, the TSR will not install.
In this situation, the socket may remain in the partially configured state that was attempted during initialization.
Example Commands
Use controller 0 and socket 0:
SBTSR.EXE c0 s0
Use controller 1 and socket 1:
SBTSR.EXE c1 s1
Specify custom IRQ configuration:
SBTSR.EXE c1 s1 i5 h10 nD000
Notes
- Options must not contain spaces between the letter and value.
- Arguments are case-insensitive.
- The program does not automatically discover hardware configuration.
