- After putting away MINIX software on the shelf for almost 2 years, a few
- days ago I decided to install the software on the hard-disk, and have
- completed that as well as compiled the OS and made a working boot floppy.
- I have a few questions that more regular MINIX user can answer:
-
- 1. It looks to me that the OS is not in 32 bit mode. Even though the
- shell /usr/src/kernel/config has 386 options, there is no klib386.x and
- mpx386.x. I compiled the OS with `config at'. Am I missing something?
- The source listing in the manual also does not seem to have those files.
-
- 2. How is the OS executing in protected mode when you hit the `=' sign from
- the boot menu? (I have a 386sx machine). Is it running in 286 protected
- mode? Or what else?
-
- 3. How can you make the system boot from the hard disk? I did
- `cp image /dev/hd1', and use fdisk to mark the first partition active.
- The system would not boot and it says `Missing operating system' (probably
- a print message from the ROM). I tried other partitions as well with the
- the same result.
-
- 4. Using the MINIX `fdisk' to partition the disk seems to always result in
- a print at MINIX boot time like `invalid partitions on winchester 0'.
- When I did the partition with Dos, the first partition start with
- Base sector 34. So I did the MINIX fdisk and made the a similar
- Base sector for partition 1, and everything worked out. Also, if the
- partition 1, starts at Base sector less than 34, mkfs seems to clobber the
- partition table. The example in the manual wasn't very clear on this.
- It seems to say that the first 2 sectors are reserved for something.
- Also the partition table shouldn't take 17kbytes to store. What am I
- missing here? ( I adusted the even sector Bases and Sizes).
-
- Much appreciate all the responses.
