The IBM PC110 can run any operating system that any IBM PC compatible computer, from the mid to late 90's can.
This could be PC Dos, MS Dos, Windows 3.1, Windows 95 (even Windows 98 at a pinch), Windows NT 4.0, OS/2, Unix even CP/M.
On my IBM PC110, I've had two operating systems. Pc Dos 7/V with Windows 3.1, also with Windows 95.
A tale of three OS's
The bios has been setup so that the PC 110 tries to boot from the hard disk.
If this is not present, then it will try and boot from the external floppy disk.
Finally, after all else has been tried, the machine boots from the internal SanDisk.
PC Dos 7
The SanDisk is a flash card that is pin compatible with PCMCIA, though much smaller.
The internal SanDisk has 4 megs of room on it. 2 Meg of this is used up with a
stripped down install of PC Dos 7. I have also added some third party software
to make the system more useable in a Dos environment.
My main control system is LapLink 3. LL3 allows me disk and remote machine access.
I can view files, copy etc. etc. The main advantage is that the LL3 footprint is
very small. I reduce the size of this further by using PkLite.
This piece of software takes a .COM or a .EXE file, compresses it and then
recreates an exectuable file that can be run from the Dos prompt. The downside
is that it takes a fraction longer to start a program, though this I can live with!
Based on information from Amanda Walkers page, I have created a boot script that will
allow me to boot to either Pc Dos 7 (English), Pc Dos 7 (Japanese) or (believe it
or not) a ZX Spectrum Emulator.
You'll find copies of my Autotexec.Bat and Config.Sys files at the end of this page.
In the PCMCIA slots I have a 240 meg hard drive. This has Windows 95 installed on it.
To give me enough room for applications, this drive has been compresssed and only a
minimal install of Win95 has been used. I have a reported 400meg free.
These is also a port for another SanDisk. These come in 4, 8 and 16 meg versions.
It is my intention to attempt to install yet another OS onto this.
The beauty of tbe PC110 is that is is incredibly easy to swap from OS to OS using
the PCMCIA and SanDisk technology.
Mainly, I use Windows 95 when I am plugged into the mains and Dos 7 when I am on the move. By doing this I can get (in theory), three hours of battery life - I've yet to test this!
