[MiNT] Memory Protection Horror Show (long)
Hi everybody,
Well I just installed the last RPMs: freemint-1.15.12-1, freemint-sbin-1.15.12-1
and e2fsprogs-1.14-6 and I tested the memory protection...
It just doesn't work on my Hades060!
First, I just renamed MINTNP.PRG into MINT.PRG and rebooted. fsck.ext2 reported:
MiNT.ext2 contains a file system with errors, check forced.
I don't know exactly what errors it found because it is very silent... (Should I
say "sneaky"?) But what it made, I know: it scrambled the flags and ownership of
several programs in the /sbin folder.
I know that this filesystem was errorless because I always use fsck.* at boot
time and shutdown to turn everything down. (Do you know how many time it takes
to check 6.8 GB split in 4 mixed ext2/minix partitions? Just a little too many!)
I used the backup of my /sbin folder to restore it because there were flags that
I even didn't know they exist... (Like: "?---S-----".) and that I didn't know
how to remove. And there I go for my second attempt.
Second, I made a copy of fsck.ext2 and fsck.minix in /boot/mint so
/sbin/fsck.ext2 wasn't any more on the partition it was supposed to check. (It
always worked but I thought it could be a problem.) I also changed the memory
flags of Jinnee to global because it always exploded. What I got was something I
never saw:
pid 1 (AESSYS): MEMORY VIOLATION: type hardware RW=r AA=FFFFFFCA PC=455776
BP=446000
pid 1 (AESSYS): Operating system killed
FATAL ERROR. You must restart the system.
That was the last time I used the memory protection. I'm fed up with it!
My setup (in which I see nothing wrong):
Hades060, 96 MB of ST-RAM
IDE 1: 3.2 GB split into:
C, D, E, F, G, H, I. (All TOS partitions except G: 500 MB Minix)
IDE 2: 6.3 MB split into:
J: 2.1 GB Minix
K: 2.1 GB Ext2 -- where all my MiNT stuff is located.
L: 2.1 GB Minix
SCSI peripherals:
M: is an internal EZ-135 (Ext2 but unused), R: is my CD-ROM. (I can also have N:
a ZIP-100 VFAT 16 bits, O: 850 MB Ext2 as backup and W: my CD-Writer... but they
weren't plugged for the tests.)
My AUTO folder:
EMULATOR
MENU
STA_VDI
XBOOT
SET_MMU
NOVACAL
PCI_BIOS
NVDI
DRVIN
SCC
BOXKITE
DMIRROR
METAXBS
CALVINO
MINTNP

Well... I think I won't include the list of the 70+ RPMs I have installed...
