Is this right setting ? I think some BIOS can change the base address
of Video BIOS.

BIOS detection failed, thus

This problem happened. Rejections of the specified video modes below
was mainly caused by this mis-configured pixel clock.

Since there are no usable mode lines, Xserver exits with error.
drivers/ati/aticlock.c in ph2v23 source tree (sorry older one,
I have not catch up with the current one) said:
* The oldest Mach64's use one of the non-programmable clock generators
* described above. In this case, the driver will handle clocks in much the
* same way as it would for a Mach32.
*
* All other Mach64 adapters use a programmable clock generator. BIOS
* initialisation programmes an initial set of frequencies. Two of these are
* reserved to allow for the setting of modes that do not use a frequency from
* this initial set. One of these reserved slots is used by the BIOS mode set
* routine, the other by the particular accelerated driver used (MS-Windows,
* AutoCAD, etc.). The slots reserved in this way are dependent on the
* particular clock generator used by the adapter.
And drivers/ati/atipreinit.c:
/*
* ATIPreInit --
*
* This function is only called once per screen at the start of the first
* server generation.
*/
Bool
ATIPreInit
(
ScrnInfoPtr pScreenInfo,
int flags
)
{
# define BIOS_SIZE 0x00010000U /* 64kB */
CARD8 BIOS[BIOS_SIZE];
# define BIOSByte(_n) (BIOS[_n])
# define BIOSWord(_n) (BIOS[_n] | \
(BIOS[(_n) + 1] << 8))
# define BIOSLong(_n) (BIOS[_n] | \

unsigned int BIOSSize = 0;
unsigned int ROMTable = 0, ClockTable = 0, FrequencyTable = 0;
unsigned int LCDTable = 0, LCDPanelInfo = 0;
(snip)
/*

pATI->ClockDescriptor = ATIClockDescriptors[ATI_CLOCK_FIXED];
pATI->ClockNumberToProgramme = -1;
ROMTable = BIOSWord(0x48U);
if ((ROMTable + 0x12U) > BIOSSize)
ROMTable = 0;
if (ROMTable > 0)
{
ClockTable = BIOSWord(ROMTable + 0x10U);
if ((ClockTable + 0x20U) > BIOSSize)
ClockTable = 0;
}
if (ClockTable > 0)
{
FrequencyTable = BIOSWord(ClockTable - 0x02U);
if ((FrequencyTable > 0) &&
((FrequencyTable + 0x20U) <= BIOSSize))
{
for (i = 0; i < 16; i++)
{
pATI->BIOSClocks[i] = BIOSWord(FrequencyTable);
FrequencyTable += 2;
}
}
pATI->ProgrammableClock = BIOSByte(ClockTable);
pATI->ClockNumberToProgramme = BIOSByte(ClockTable + 0x06U);
switch (BIOSWord(ClockTable + 0x08U) / 10)
So if BIOS detection failed, then it will cause the failure of Clock
detection, I think.
see doc/README.ati also.
