To find people with good knowledge about those old notebooks is not so easy. Who knows how the software is configured. The notebook is about 12 years old.
The fact is that old Satellite 230CX is not supported for Win98 and you should be happy if notebook runs well with supported Win95.
Satellite 4070 is supported for Windows 98 and on Toshiba support page you can find drivers, tools and utilities. I recommend you to make clean WIN98 installation first.
The way I did it was to run Win 95, click start, shut down and restart in DOS. At the DOS C:/WINDOWS prompt, type format C: then hit return. Wait for the hard drive to format, then pop the Win 98SE disk in the drive, restart the PC and choose run from CD ROM. You should then be able to install 98SE.
I assume that you have a CD ROM drive
I have another 230CX that I need some memory and a hard drive for, can anyone help?
I have a working 310ctd machine complete, bar battery us and a tape repair to the lead on the ps. If your looking for spares, this one is available for £15 plus postage at cost. Mail me if your interested,
