Hello:
I little more information and a correction.
My hard drive is the master on the secondary IDE channel i.e. /dev/hdc2
As promised in Chapter 2
We are making progress I got what looks like a linux boot process
Stuff is a flying by, This is what is left that has not scrolled off the
screen:
(abridged of course, remember these notes are taken by hand)
The puts 1 to puts 16 are off the top, but they did go by.
PCI: Probing PCI hardware
Linux Net4.0
Initializing RT netlink
KERNEL After sock_init
KERNEL After start_context
KERNEL After startup NET5 MYSCS DECNET
starting kswapd
pty 256 Unix 98 ptys conf
Serial driver
ttyS00
ttyS01
block 128 slots
NET4
IP Protocols
IP routing cache
TCP Hash tables
NET 4
KERNEL-I-DEBUG After do_initcalls
KERNEL-I-DEBUG After do_basic_setup
request module [block-major-22]:Root fs not mounted
VFS: Cannot open root device "hdc2" or 16:02
Please append a correct "root=" boot option
Kernel Panic: VFS: Unable to mount root fs on 16:02
Notes: If you/me set the line
kernel /bzImage root=LABEL=/
the output is:
KERNEL-I-DEBUG After do_initcalls
KERNEL-I-DEBUG After do_basic_setup
KERNEL PANIC I have no root and I want to scream
but if you/me set it to
kernel /bzImage root=/dev/hdc2
the output is:
KERNEL-I-DEBUG After do_initcalls
KERNEL-I-DEBUG After do_basic_setup
request module [block-major-22]: Root fs not mounted
VFS: Cannot open root device "hdc2" or 16:02
Please append a correct "root=" boot option
Kernel Panic: VFS: Unable to mount root fs on 16:02
So root=/dev/hdc2 looks more promising so we will work with that.
In checking my /dev directory, I see my hdc2 major number is 22 and minor is
2, looks good.
and I going to assume 16:02 is just hex output for 22:02
In reviewing my linux boot process the output is almost identical and this
about where the VFS code is invoked.
Notes ( more notes about those puts you see flying by)
Located in /home/andrewa/freevms/linux/init/main.c
After puts 1 it calls lock_kernel
puts 2 linux_banner
puts 3 setup_arch
puts 4 printk
puts 5 parse_options
puts 6 trap_init
puts 7 init_IRQ
puts 8 vms_init
puts 9 sched_init
puts 10 softirq_init
puts 11 time_init
puts 13
puts 14 console_init
puts 15 init_modules
puts 16 kmem_cache_init
Sorry no more numbers
after mem_init before lnm_init
after lnm_init
after kmem_cache
Posix conformance testing by UNIFIX
do basic setup
After sock_init
After start_context_thread
After do_init_calls
prepare name space
After do_basic_setup
DISCLAIMER: WHAT NOT TO DO unless you have some spare time to waste.
At least there is a gem or two of knowledge to be learned from the process.
So back to the ext3 stuff
In checking my notes I discovered that I had commented out the EXT3 option
in the depend stuff.
So lets put that directory in - sounds reasonable doesn't it?
lets create a directory /home/andrewa/freevms/linux/fs/ext3
copy the files over
edit the makefile in /home/andrewa/freevms/linux/fs
uncomment the line subdir -$(CONFIG_EXT_FS) += ext3
cd /home/andrewa/freevms/linux
make dep
Cough Cough
It's complaining about some .depend file in /ext3
Huh?
Lets check nope not there.
Go back to the linux sources yah its there
Note to self (GEM Alert) cp * /home/andrewa/freevms/linux/fs/ext3 doesn't
copy the .hidden files
Got to do that literally
Ok lets try that again
make dep
Cough Cough
Huh?
Checking again
Oh doesn't have write privileges chmod +w
make dep
Cough Cough
Huh?
Checking again
Opps wrong owner I did this all as root
chown andrewa *
Note there that * problem again
chown andrewa .depend
Ok make dep
make bzImage
copy files and reboot
Nope same kernel panics
Well that was a complete waster of time.
Back to File Basics 101
Later Andrew
