When I run CIM, ASRS can not start-up. (DSP computer)
Switch on the ASRS, floppy drive of ASRS can not work, but the fan of ASRS can run.
What can I do? Can you help me, thanks.

Are there any messages on the screen ?

Try pressing Ctrl+Alt+S when the ASRS is powering up, this will get you into BIOS, in BIOS make sure the drive is set to 3-1/2" and not 5-1/4" drive

It could also be a faulty disc drive

ASRS Cyclone Tu150 DSP SETUP
CMOS SET-UP
(Rack type p.c's)


If the p.c. is left with power disconnected for a long period of time, the on board battery may become drained.
This results in the p.c. suffering a "loss of memory".
To re-establish settings use the following procedure.

Turn on computer.
When screen displays:
Starting MS DOS.......
Depress Ctrl+Alt+S keys simultaneously to invoke the set-up procedure.
A menu will now appear in the centre of the screen giving set-up options i.e.;
Setup
Extended BIOS Features
System Information
System Security

Using the cursor keys highlight the option "setup", and press return.
Screen will display certain values.
Adjust values to 3-1/2" floppy drive 1.44 M then press F10.
A dialogue box appears to confirm that the changes have been saved.
Press Esc twice to exit setup.
The p.c. will now reboot.

"For information only"
The only thing I remember about the 'special' floppy drives were... - They were Sony drives - Their case had to be electrically isolated from the chassis of the machine – i.e. the metal case must not touch earth. Something in the back of my mind thinks that they may have had their ribbon cable connected the 'other way round' to a normal drive so in order to use a 'normal' drive on a DSP computer you had to cut the ribbon cable header connection tab off, to be able to insert the cable into the drive the 'wrong way round' Cut this tab off v
