DiskOnChip Problems
\
-
Once the DiskOnChip is installed into the motherboard the amount of
time it takes for the system to boot increases significantly (about 2
minutes longer). The DiskOnChip data sheet explains the BIOS first
identifies the device and then the DiskOnChip executes the code stored on
the boot block that loads the TruesFFS software into the host memory. Would
this be the reason for the increase in boot time or does 2 minutes seem to
long just to identify and load software for the DiskOnChip?
2. When I write a file to the DiskOnChip from the hard drive the system
acts sluggish (mouse does not respond quickly). Reading a file from
DiskOnChip has no effect on performance. When I write to DiskOnChip is it
affecting my interrupts? I have tried passing various option to the
DiskOnChip driver with no effect on performance.
3. Has anyone had the same problem with DiskOnChip with QNX 6.3 or 6.2?
If so how did you overcome it? Any suggestions or help would be
appreciated.
