What program do you use to burn a Tiny Core ISO in a CD-R?

[jazzbiker]

I don't know, I remembered suddenly about automount. Probably fdisk will refuse to edit mounted partitiion. So what is the progress with 'w'?

[jazzbiker]

Well I'd sync manually once again to be sure :-) Yes, it would be interesting to check the homework.

Sorry for being so annoying, but how to sync that disc manually? 

[jazzbiker]

Code: [Select]

sync

I think no need, everything is ready.

Oops... Nothing, I get the same Welcome to GRUB! GRUB loading. and then reboot loop.

Have You seen this computer boot something and if yes what was the happy booter?

So this PC was stored for a couple of years. About a month ago I tried to turn it on and it turned on but it gave no video. I did some searches and found a post somewhere that told me to first change the BIOS battery and try again, and it gave video.

This PC had Windows XP on it. When the PC booted it asked for some Windows repair CD or something, but I didn't bother me too much since I don't use Windows  and tried to install TC on it directly.

An alternative way to try the Plop Boot Manager for booting the CD is to install the boot manager on the original HDD using another computer, similar to what you've been trying. You might need to repartition and format the HDD first, with the first partition FAT formatted. Using a floppy would still be easiest if you can. Old PCs like booting from floppies, everything else makes them cranky.

Hi!
I can not understand why GRUB can not find the data on the disk. It reads some data from BIOS. Are these data fake? But we can not repair this. Can this box be kind of hardwired for Windows only?

In order to exclude InstantCore.img issues I've wrote it to 4.3G HDD of my ancient Toshiba laptop with P1 and 64M of RAM. No CHS adjustments, just as is and everything was smooth excepts screen resolution (got 640*480 instead of 800*600) but it was expected. GRUB menu appeared, kernel loaded, TinyX desktop worked normally.

Toshiba SatellitePro 480CDT.

Unfortunately @Mauricio's box has tricky BIOS, and I don't know, what can be done.

This sounds like could be a solution, I gotta see if I have some floppy disks somewhere, I hope the floppy drive of that PC works so I plug it on another one to write the floppys. Never used floppys before, quite an adventure!

Now that you mention the hardwired thing, I noticed the motherboard has some kind of switches. Here I found a photo of a random motherboard that has a similar one (the blue thing): https://image.shutterstock.com/image-photo/computer-motherboard-chip-view-dip-260nw-49645546.jpg

@Mauricio, can you confirm that any of the CDs you burnt will boot _any_ machine?

can you also confirm that the default bios settings have been selected, saved, and applied?

if you can't find the specifications and instructions for that exact motherboard model and version then please double-check all the numbers and then put them in a post so that we can also do some searching.

I took a look at the BIOS.

The PC is a Compaq Deskpro EN Series SFF. Maybe I can find some datasheet or manual that says something about the configuration of those switches?

Other thing I noticed at the Storage tile, IDE Devices, Primary Drive 0 is 8182 cylinders, 16 heads and 63 sectors. Maybe the repartitioning failed? I setted up different values yesterday.

I tried booting a CD on another machine and it booted fine.

I just resetted the BIOS to defaults and now I get the previous error message:

Code: [Select]

GRUB loading.
Welcome to GRUB!

error: disk 'hd0,msdos1' not found.
Entering rescue mode...
grub rescue>_

The difference is that now I can use the keyboard and type things on that screen.
