Well, here again. Thanks for the advice, bigpaws.
I write at the same time I'm trying several things.
First, some findings:
- an option in BIOS that says: "Large Disk (can't remember) Mode", with the options "DOS" or "Other". It suggest to choose "Other" when using UNIX, Novel or other OS.
Changing this option to "Other" didn't work althought the installation reached to 4% and failed as before.
- doing a dmesg after a failed installation showed some messages:
"buffer I/O error on device hdc,logical block..."
"the failed read 10 packet command"
and many more.
I have searched this messages in internet an read some suggested solutions (most coming from Ubuntu forums):
- change the CD-ROM drive -> not possible right now.
- using some switches (as suggested by Bigpaws) like acpi=off, noacpi, irqpoll, etc. Tried some of them, but didn't worked either: the installation failed at the same points.
- removing a RAM module (because it could be playing bad with the CD-ROM drive)... I removed the 128MB RAM module, leaving the system with the 32MB RAM original module. Then, run the install by typing "linux acpi=off noacpi irqpoll".
And you know what? The installation have advanced over the point when it used to fail.
All the .tlz files were copied very fast (so, I suspected something went wrong), then it installed all the software I have chosen (I did a default install, just to test, so all software was going to be installed).
But after rebooting the first time (after all files are copied) the OS didn't boot. I have tried using "linux root=/dev/hda1/ ro" as it's suggested but... no luck (don't ask me exactly what happened).
So, right now, as I'm writing this, I'm performing a new installation, from zero, with just 32MB RAM and booting just "linux" (w/o any switch).
And you know what? It has advanced to the 5%... very very slow.
I will wait and then come back to report the results.
I hope I can add my 128MB RAM Module after installation, (if installation is a success)...
What do you think?
Thanks again and excuse my rough english.
