Hello, 

I am not really sure whether it's worth a PR, that's why I am writing here:

Environment: 
2xPPro/200 256Mb RAM; Asus P/I-P65UP5 motherboard, CPU card is Asus C-P6ND

1) kernel as of 25th February, 1998, no options MAXMEM defined. 
2) kernel's as of 12th of March, 13th of April, 14th of April.

2nd variant kernel's will boot, but recognize only 16 (!) mb of RAM, when 
the hardware itself recognizes 256Mb, in case if MAXMEM=(1024*256) is not
defined.
Otherwise, adding MAXMEM (which is, as far as I recall, obsolete),
everything is ok. 

There're another machines, which work with MAXMEM not defined (i.e. recognize
all of their 256/512 Mb ok)  with all of those above mentioned kernels. Their
hardware difference is that they are 440-LX (Redwood).

There're no BOUNCE_BUFFERS in any of these kernel's configurations.

Quite strange.
