doc2000 problem

I am sorry to write another mail as I use a bad mailtool.

And I find this head in the diskonchip.c.
/*

So I think there is no problem you metioned.

I use the  mtd-util-20011008.tar.bz2. It should not have BBT problem.

I use the right position,and it shows this:
Dec  8 10:23:52 localhost kernel: Using configured DiskOnChip probe
address 0xd8000
Dec  8 10:23:52 localhost kernel: DiskOnChip found at 0xd8000

I read this from mtd/device/docprobe.c.
static unsigned long __initdata doc_locations[] = {
#if defined (__alpha__) || defined(__i386__) || defined(__x86_64__)

I run MAKEFILE.
It return like this 
mtd* file exist.

flash_eraseall -j /dev/mtd1
it doesn't recongize the device.
it return no such device.

Then what should I do??
