System Expansion
Hard disk
Toshiba T3100e came with either a 20 MB hard drive, and the T3100e/40 came with a 40 MB hard drive. Some models marked just “T3100e” (not “T3100e/40”) also came with a 40 MB hard drive. The system has a standard IDE interface to connect to the supplied Conner CP hard disk.
These are the drive configurations supported by the BIOS:
| Model | BIOS type selection | Cylinders | Heads | Sectors per track | Capacity | Seek time |
|---|---|---|---|---|---|---|
| Conner CP-3022 | Type 11 | 615 | 4 | 17 | 20 MB (Formatted 21.4 MB) | 27 ms |
| Conner CP-3024 | Type 11 | 615 | 4 | 17 | 20 MB (Formatted 21.4 MB) | 27 ms |
 | Type 12 | 980 | 5 | 17 | 40 MB (Formatted 42.8 MB) | 25 ms |
This system can be expanded with an 8-bit and 16-bit ISA expansion cards. Hence, you can purchase an XT-IDE adapter to add a hard drive, such as the XT-CF-MINI or XT-CF-Lite card to add a Compact Flash card as a hard drive. They usually run for $40-$60. You can find them on eBay. Check out http://www.malinov.com/Home/sergeys-projects/xt-cf-lite and https://shop.bluelavasystems.com/products/xt-cf-mini-bootable-8-bit-isa-cf-card-interface-xt-ide
Another option is to purchase an XT-IDE adapter for the Toshiba proprietary expansion slot. There is a maker on eBay that sells Toshiba type expansion cards with XT-IDE to allow many different types of IDE and CF cards to be used on the portable computer. Please see the following link for the sales article. 3inONEder: Toshiba Portables (affiliate link)
Audio and ethernet
The same adapter that allows you to use the Toshiba proprietary slot connector for XT-IDE and custom hard disks also optionally allows to add audio (Adlib) and ethernet support (partially NE2000 compatible).

Questions and Answers
Q: My computer gives me a CMOS error
A: If the CMOS battery is empty, you will be prompted with the following error when you power on the machine.
**** Error in CMOS. Bad check sum **** *** Error in CMOS. Bad memory size *** ** Error in CMOS. Bad configuration ** Check system. Then, press [F1] key.....
Please refer to instructions here:
How do I boot my T3100e with an empty CMOS battery
Q: How can I access the built-in BIOS ?
A: Press CTRL + SHIFT + F10 when the computer powers on. If this does not work, you may use the TEST3.EXE utility, a little program by Toshiba which will open up the BIOS settings from a DOS environment. You might want to include this utility in your computer recovery disk. See below for files that apply to this type of machine, or view all files at the files and resources section.
Q: I am still unable to access the BIOS.
A: When the computer BIOS battery runs empty, it will clear all BIOS settings and will prompt you to review the system settings on power-up. This may be used to your advantage to get into BIOS. To force this behavior, disconnect the clock battery entirely. Wait for a few minutes and power up the computer again. The computer will ask the user to review the default settings. Please refer to How do I boot my T3100e with an empty CMOS battery
Q: My computer does not hold settings or time
A: You probably have an empty BIOS battery. The battery holds volatile information in a CMOS chip like information about your BIOS settings and system time. When the battery runs out, the information will be lost. You can still use your computer by going into BIOS settings and accepting the defaults (see above).
Q: How do I replace the computer BIOS battery?
A: The BIOS battery is located on the system board. The correct voltage for the battery is 3.6V. You can replace it with either an original part, such as the Saft LS14500 Lithium 3.6V battery, or alternatively, you can replace it with a 3.0V CR2032 coin cell battery. If you are using a coin cell battery, get a CR2032 coin cell battery holder and a CR2032 lithium battery. Take the old battery connector and its wires, solder the coin cell holder to the existing wires like the following:
