(I posted this problem a few days ago, but I have some more information
now)


I recently aquired a couple of 8M SIMMs to increase my system's memory up
to 32M.  However, NetBSD 1.1B will not work now, and panics with a "ptdi:"
message right after "biomask, netmask, ttymask" when I boot with 32M
installed. 

However, the exact same system with 32M works fine with a generic NetBSD
1.1 kernel, as well with Windoze.  At first, I thought the problem might
be related to my BIOS and EXTMEM_SIZE, but no EXTMEM_SIZE setting worked,
and the generic NetBSD 1.1 kernel doesn't use it.  I have also tried
compiling a similar 1.1B generic kernel, but it fails just like my usual
kernel.


Details about my system:

Dell Dimension XPS P133c
  Triton motherboard, 256k PB cache
  32M RAM - 2 8M SIMMs (EDO) in bank 0, 2 8M SIMMs (FPM) in bank 1
  NCR 53c810 PCI SCSI adapter
  Number Nine Motion 771 PCI video card
  Sound Blaster (clone) ISA card

NetBSD 1.1B - Kernel current as of last night


I really have no idea what is wrong here.  The only things unusual in the
boot messages are a few extraneous devices.  For example, 1.1 & 1.1B say
that I have a sea0 and ie0 devices.  1.1B additionally says I have ie1.  

Here is the boot message for a successful NetBSD 1.1 GENERIC boot.  The
kernel is the same as a the KOTH kernel, except sd0a is compiled in as the
default root device (because of BIOS problems with the SCSI card).  I
can't save a 1.1B bootup because it panics, but I'll note the
differences:
