[comp.sys.atari.st] Problems with TOS 1.4

UPSYF173@DBIUNI11.BITNET (Wolfgang Thiel) (03/27/90)

     I have problems with TOS 1.4 which may be related to this topic:
1. After a warm reboot (I think even cold boot) the Harddisk driver is
   not loaded.
2. I sometimes get an R/W error on the harddisk (which I don't think is
   a problem of the disk)
3. Drive A: will sometimes be corrupted (root Directory written into
   FAT sectors, as far as I remember).

Installation: SH205, CBHD3.5 Driver, GEMINI installed to autostart.

What helps for 1. and 2. is to turn off the harddisk and turn it on again,
nothing else.

I have some theories about the problems:
1. a virus (I don't think so!)
2. A bad driver blocking the DMA (CLAUS BROD, are you on the list?)
3. A memory allocation failure of the TOS
4. A floppy vbl routine that blocks DMA
5. A critical error handler that does something wrong

The #3 problem may have been caused by me formatting disks under MSDOS,
so that a mediachange was ignored (no different serial numbers in the
boot sector). So I don't complain about that.
But there's another mystery:
After autoboot of GEMINI (which lives in C:\DIV\GEMINI on my harddisk)
the first file selector box will only show the subdirectory; the only
possibility to get to the root directory is to click on drive C, the
closer box does not work.
     Anyone else with nice little theories?
