Hey guys,
in this topic I am going to offer you a copy of my floppy image with all the real mode drivers for the fujitsu lifebook 770tx notebook.
It is complete, I was able to get the USB port, pcmcia sockets, sound card, mouse, extended memory and support for fat 32 partitions.
Unfortunately, I couldn't put the drivers for the integrated CD-ROM because my notebook didn't come with a CD-ROM, just a battery and a floppy drive.
In my case this was not a problem as I am using an iomega usb cd-rom drive, which was normally supported and I was even able to obtain audio cd sound.
As for the pcmcia socket, I use a compact flash adapter for pcmcia, put a 256MB card and use it to add new things to drive c.
In the usb port I could get operation for cd-rom drives, pendrives formatted in fat and fat32, input devices were not supported.
This is my first topic here, I hope I'm not violating any of the site's rules, before posting I looked for similar topics to make sure I didn't do it.

• Attached file is .img, use Use RawWrite for create disk.
• I configured the pcmcia services so that slot 0 is standard for compact flash cards, that is, in slot 1 the cards will not be mounted. If you wanted to go deeper, search for PhoenixCard Manager on google.
• Maybe before to use a compact flash it's necessary to use the PCMFDISK.EXE tool to create a correct partition, then just format using FORMAT.EXE (All data is lost!).
• Other things like DOS commands, changing drive letter and managing memory I won't mention here because they are goodies that every DOS user should know 😀
• In case I improve this in the future through batch scripts, I update this topic.
