Toshiba 1100 Plus Laptop

[dennisking4]

My computer does not cold boot to Toshiba DOS 3.2. It, on cold boot, requires sys disk. When installing system disk it works fine. I was under the impression that T1100 Plus had 3.2 DOS in ROM and should cold boot without system disk. Can anybody provide any further information reguarding this problem I am having? Thanks dennisking4.

Have you tried the SETUP10.zip (http://paulbrett.plus.com/tmp/SETUP10.zip) to see of the boot options need to be altered?

Paul.Brett thank you for your input. With the setup10.exe it is for T1000 only. It will not work on my system. But I thank you for the input. dennisking4

I can see Internet documents that indicate that the T1000 and T1000SE contained DOS in ROM, but not so for the T1100+.
For the T1100+, I see:

1. A review that includes, "In addition to the Toshiba with built-in synthesizer, my $2395 got me MS-DOS version 3.20,"

2. A Toshiba T1100+ sales phamplet that includes, "Operating System MS-DOS 3.2"

3. Specs which include:
"Toshiba MS-DOS 2.11 shipped with early models"
"Toshiba MS-DOS 3.20 shipped with later models"
"Toshiba MS-DOS 3.30 (includes diskettes and manual)" as an optional extra

Can anyone say for certain that the T1100+ contains DOS in ROM ?

Hello modem7. My T1100+ has the same logic board as a T1000 except for the 80c88 for the T1000 and a 80c86 for the T1100+. The bios are identical. I have both logic boards in my possession. Thanks for your input dennisking4.

By that are you saying that someone has replaced the motherboard in your T1100+ with a T1000 one (and swapping over the CPU)?

If not, I would expect that apart from a CPU difference, a T1000 and a T1100+ motherboard/BIOS would differ at least because:

1. T1000 runs at 4.77 MHz, T1100+ at 7.16 MHz. In the T1100+, chips in addition to the CPU would probably have increased speed ratings.

2. T1000 runs at 4.77 MHz, T1100+ at 7.16 MHz. Either the T1100+ has different clocking circuitry, or something in the T1100+ BIOS switches the clocking circuitry up to the higher speed.

3. Surely something in the T1100+ BIOS indicates that the machine is a T1100+. It might be just a string like "Toshiba T1100+" but I would expect something that would quickly enable a hardware dependent program (such as a Toshiba support tool) to quickly identify the model.

I have the manuals, and I am pretty sure there's no ROM in the Plus.

Hello Billdeg. Upon further searching I am quite sure my T1100 Plus Toshiba is software controlled and not ROM controlled. I thank you all for your input and if I can of further assistance to you with other computers let me know. Thanks dennisking4.

That was cool that ou found that out. Did you use an online source?
