# Dummy boot block
|
|
|
|
The `noboot` code simply prints the message
|
|
```
|
|
++======================================++
|
|
|| This is not a hardware bootable disk ||
|
|
++======================================++
|
|
|
|
CPU WILL HALT
|
|
```
|
|
and halts the CPU. The entry point is 0 and can therefore be started
|
|
with a `clr pc` as is done on boot PROMs. Code like this is used as a dummy
|
|
boot block in non-bootable disk volumes. The `lda` file is also useful in
|
|
PC11 loader tests.
|
|
|
|
### Start on w11
|
|
See general notes on
|
|
- [FPGA Board setup](../../../doc/w11a_board_connection.md)
|
|
- [Rlink and Backend Server setup](../../../doc/w11a_backend_setup.md)
|
|
|
|
To run the `noboot` code use
|
|
```bash
|
|
ti_w11 <opt> -w -e noboot.mac
|
|
```
|
|
with the options `<opt>` as described in
|
|
[Rlink and Backend Server setup](../../../doc/w11a_backend_setup.md).
