I found a workaround (see below) and have a working system that boots fine from a DVD thumb drive, but I am still interested in solving the DVD boot issue if I can.
To answer the questions above, I am using the standard 32-bit Tinycore. I tried another computer (Dell 745, Core 2 Duo, 2GB RAM) but the results were the same.
Re: "It looks like tc booted too quickly for the cd/dvd drive - did you try the menu options for slow devices?", my USB thumb drive with TinyCore shows that menu when it boots, but the DVD just dumps me to the command line as it boots -- no menu options shown. It seems to me that the boot process waits long enough for TinyCore to boot and give me a working kernel and shell, but for some reason isn't showing that menu that happens at the very start of the USB stick before it boots successfully into the GUI. Any suggestions would be appreciated.
Here is the workaround I used to get it running.
[01] Prepare a formatted FAT32 USB thumb drive.
[02] Plug it into a computer running Windows (Spit!) XP, Vista, or 7 (I don't know about 8 or 10)
[03] Put a DVD made with the CorePlus-current.iso in the DVD drive.
[04] Download core2usb.exe from sourceforge.net
[05] Run core2usb.exe (it's a standalone -- no install)
[06] Follow the instructions for loading TinyCore Linux to the thumb drive.
[07] Boot from the thumb drive (it has to be before the DVD or HDD in the BIOS boot sequence)
[08] It should boot into the TinyCore GUI (it did for me)
[09] Follow the instructions in the corebook to load and run tc-install.
[10] Now you can install TinyCore on another thumb drive using ext4 or one of several other formats.
[11] If you want the new thumb drive to be able to install or remaster, It will get the files to do that
from the DVD.
So now I have a working system, but darn it, I want to do it without dragging out my old Windows box!
BTW, TinyCore does everything I want it to do, boots faster than any distro I have ever tried, and at 15MB it fits on those old, small thumb drives we all end up collecting along the way. This one is definitely a keeper.
EDIT: I will try the suggestion from the other thread (using the 9MB CLI version to install the larger version) and report back.
