I am trying to install QNX from the install CDROM to a 256MB SanDisk on a
Kontron PC/104. We have a batch of 256MB SanDisk compact flashes; some of
which will install and some of which will not. In all cases, the disks come
preformatted with DOS and are seen by the BIOS just fine. The problem is,
after I have entered the serial number from the installation CD, it prompts
me for the installation drive. Unfortunatly, in many cases, no drive is
After some investigation, I noticed that there is a difference between the
compact flashes. The “Auto” mode in the BIOS setup returns the following
information for the working drives: 695cyl,15hds,48sect (256MB, 50400
sectors). It returns the following information for the non-working drives:
980cyl,16hds,32sects(257MB,501760 sectors). I checked the partition
information in both cases and they both show 256MB DOS partitions with the
BOOT sector enabled (in both working and non-working cases). I even
attempted to format a partion with a bootable QNX partition (77) via fdisk,
but to no avail.
Do I need an updated driver to support the different flash configuration?
Is the BIOS not reading back drive info correctly using the AUTO selection?
Any information here would be helpful.
