I would recommend also looking into a newer DOS than what is on that thing. Aim for 5. Also if its an SX chip don't expect anything amazing to happen :P
I managed to get the software on the diskettes for the laptop, however after trying to run disk a it kept on failing. after rebooting the laptop have now got another message
"610-External storage device failure hit F1 when ready"
I have the feeling that the front floppy has failed since it was making a lot of noise when I inserted the disk.
I have also found a booklet on the LTE laptops which explains the error, however i dont understand what it means.
The floppy is bad. If you "burned" the floppy yourself you might want to look into finding fresh disks or keep going through them till you find working ones.
I just thought realised I forgot to tell you, that I am using the built in floppy drive in the laptop. this could make it a bit more difficult to get it out of the laptop and have and see if they are any issues.
On looking up the error message I found a manual for a newer model of the computer I have.
In the manual it says;
Switch 3 on vertical circuit board is set for an external drive but no tape or diskette drive is installed in the expansion base.
Under a cover on the bottom of the laptop is a DIP switch. This is a manual override that companies used so that nothing could fuck up BIOS wise. Look up a grid of what all the DIP options are.
