SQUALLY SHOWERS. GOOD.
Depending on architecture the IO address space can be:Quote:>sorry cos its not a unix specific question. i noticed that some

In either case the addresses in the IO address space are mapped to the
memory units on
the device board...
Input/Output range E800-E8FF
Memory Range - FEBEFC00-FEBEFFFF -> pl explain this
Interrupt request - 10
Intel box and the NIC is on a PCI slot.

It means there is hardware on the board that respondsQuote:> Input/Output range E800-E8FF

There's also often hardware on such boards that
can do DMA (Direct Memory Access), so the board
can makes it's own accesses to system memory
without the intervention of the main CPU.
Here is a dumb question for you. Is the synchronization range (Which
Redhat 4.2 claims is in our monitor's manual) the same thing as the scan
range? My manual (for Gateway 2000 Vivitron 17'')specifies the scan
frequency (31.5-80 kHz Horizontal; 50-100 Hz Vertical) but there is
nothing mentioned of synchronization.
I have tried substituting scan range for sysnc range during the setup,
but I can not get the XFree86 (or any other X) to work. I have also
tried to extract information about synch. from the Windows 95 control
panels. But sysnch parameters appear to be a discret set of '+' or '-',
not a range of frequencies. So I am confused about what exactly is meant
by synchronization. Also I am confused on how the "refresh rates" fit
I am hopping that someone who has successfully used Gateway 2000
Vivitron 17'' with RedHat 4.2 can tell me what numbers should I put for
vertical and horizontal sync rates. In general the redhat installation
does not have an entry for this monitor, so I also appreciate getting
advice on what other parameters I should customize (chose VGA or
SuperVGA, etc.). I use the Win95 settings of 16 bit, 600x800 resolution.
Thank you very much,
