[ cc to Mdk Expert, in case anyone else has helpful advice ]
the retailer -- to whom i returned the Soyo Dragon Ultra KT400 mobo --
told me that Soyo had recalled them & were replacing them with new ones.
last week, i picked up a mobo, which i assume is a replacement
(i forgot to make a note of the serial numbers)
& i have now reassembled the box & tried it out.
it seems to be an improvement at the BIOS level:
it recognises the processor as 'AMD XP 2500+' (correctly)
& defaults the DRAM clock to 166 MHz (previously it set it to 133 MHz ).
however, there's a new problem: Linux won't start!
i had installed Mdk 9.1 , which is still there of course,
& Lilo comes up properly & tries to boot the system,
but fails with a kernel panic, which is quite new (Linux was ok before).
the lines on the screen are as follows:
Unable to handle kernel NULL pointer dereference
at virtual address 00000000
printing eip: c02360d0
*pde = 00000000 Ooops: 0000
there follow a dozen lines of registers, call traces etc, then:
<0> Kernel panic: Attempted to kill init!
spurious 8259A interrupt: IRQ7
(the last line occurs only some of the time:
it's the printer IRQ, but i haven't defined a printer on the box yet).
i tried (1) Lilo with 'nofsb', 'failsafe' & 'linux rescue': no difference;
(2) BIOS set to 'failsafe' & 'optimised': no difference;
(3) Mdk 9.1 boot diskette: no difference;
(4) Mdk 9.1 CD1 : Lilo starts regardless, even with 'hdd1' given priority
(BIOS does recognise the HDD & CDD correctly);
(5) Mdk 8.2 boot diskette: boots, but can't find 'init':
it expects a ReiserFS, which i have on the existing box;
(6) checking h/ware, ie memory & drive cables: all firmly in place;
(7) DOS diskette: boots & accepts simple commands;
(8) RAMF-118 rescue diskette: ok & allows 'mount /dev/hde1 /test',
then 'cd test' & 'ls etc' showing the appropriate files,
so the problem doesn't seem to be damage to the HDD.
this problem is new to me: anyone have any suggestions what to try next ?
