Thanks!!
I wasn't able to find it. The bios collection is very nice (i also own a 110cs and saw it was in there too).
So i updated my bios from 1.10 to 2.40 but it didn't change my problem.
It is quite complex, but to sum-up :
- i bought this T1910cs many years ago in a fleamarket, i know nothing about its past. Back at home it wasn't working at all.
- one month ago i found it and i decided to have a closer look, i changed all the caps of the motherboard, since that it powers on!
- the screen stayed black, finally it was only a problem with the standby contactor, win3.1 displays in color, nice!
- the floppy drive was dead, and moreover i cut by accident the flex cable which was very specific (normal 26pins cable wide on the mb side and larger on the floppy side)
- i put a common 26 pins flex cable, and a "modern" floppy drive : was not be able to read floppy disk
- i tried with an other one, guaranteed and tested drive : same result..
- at end i dscovered that it was perfectly working with 720 kb disk! but nothing with 1.44 mb.
I don't understand why, i did many control on the motherboard about the solders i've done with the caps but it looks good. The connection is good between the flex cable and the mb connector.
It simply doesn't want to read and write 1.44 hd disk...
I did some searches on the web but found nothing, looks very uncommon.
I know that this computer is designed to be compatible with these disks, but when i saw that i have a such old bios version i thought it was maybe a solution.
If you have any ideas...
