In May 18, we finally installed linux0.11 on a real PC.

By the way, this task can be really long, and it may take a few months to drag and drop. In the middle, I stopped to learn something else and put down the Linux thing ,, until I saw Ralf brown 'interrupt list, but the purpose of this installation is to learn Linux. The next step is to study harder and harder ,, there is also the network part, and strive to install the network part of linux1.0 to 0.11:>
I would like to thank myself for not being as lazy as usual in the afternoon. I had to switch the hard disk from slave to master in the dismounting box. In fact, the kernel of linux0.11 can be used without any modification ,, of course, from the result:>
The two days are depressing mainly because the hard disk is slave and the master is broken. As a result, a reset like port 0x1f1 returns 7f, which is always wrong. It will be much better after the change.
Actually, if (drive> 1 | HEAD> 15)
Panic ("trying to write bad sector ");
Because the head of the hard disk is larger than 15, and the hard disk must use normal mode, but I don't understand, isn't the normal hard disk only accessible to the 520 (or 512) MB hard disk range ,, while my minix partition has obviously exceeded, and, continue learning !!
Execve () of linux0.11 can only execute the oldest A. out file. At the beginning,/bin/sh copies bash in rh9, which is in the ELF format and cannot be used.
Take notes when you study things again. It will take a long time to get down and get down for 2nd times.

The section in the Ralf brown 'interrupt list that I checked a few days ago is related to the IDE:

Hello, zmba!

I was wrong. I didn't understand the purpose of linux0.11 in the past, but I learned about the kernel and the current kernel through 0.11. At that time, this passed and was another opportunity, put in the past ....
