If the BIOS on startup isn't seeing more than 016000b of memory, then you have a BIOS problem, not a kernel problem.
Try flashing the BIOS if it supports it
Adding the mem option AFAIK doesn't *bypass* the BIOS, it simply tells linux what memory you have if linux reads the BIOS wrong.
To my mind, you have a hardware problem, not a software problem (unless a BIOS flash can fix it).

Is there not a bios option to redetect memory? and are you sure the Simm
is
really a 32MB simm? also does the motherboard of your machine recognise
more
than 16MB simms etc? how many simm sockets does your machine have? must

install large simms in pairs? is the memory speed, parity etc. etc.
correct for
this motherboard?
Not sure if the motherboard can recognise more than 16MB (a clue is that the boot sequence registers 016000KB, I guess that the preceeding 0 means that it might recognise more) - but what I wanted to do was bypass the motherboard BIOS. The 16MB was EDO 60NS Parity - same as the 32MB (I've tried the 32 in other machines where it seems OK). The machine (an Amstrad PC9486) has one 72pin socket, and 4 x 30 pin sockets - these can't be used together, and so 72pin SIMMs can't be installed in pairs.
They are all the things that first come to mind with this, you could also perhaps try booting from alternative boot media with the memory options to
see
what happens to rule out it being something to do with the kernel on the machine.
I've tried with TOMSRTBT, but I'll try passing some of the options at boot time.
PS you havn't got the 2 modules mixed up have you and inadvertantly put
the
16MB simm back in instead of the new one? ;)
No I'm pretty sure I've got the correct one, and anyway when I try the append option to address 16MB the machine still fails to boot. I'm sure that there is something wrong with the way I'm editing the lilo.conf script.
