I have an old PC where the disk is a 32mb IDE flash module. BIOS boots the Flash, works good.
But if I am in a Linux distro (tinycore/arch/puppy) the flash module is not recognized nor mountable.

On the flash module there is a custom Windows MCE powered by Gio. I want to replace that with a Linux kernel but I failed trying to access that memory so far.

I already tried setting the jumper in every variation.
Could it be that the Manufacturer prevent access to it in BIOS?

Below is a picture of the flash ide module. Maybe someone has an idea how to format this?

What's the manufacturer and model name? Under Linux (preferably a live distribution with ample hardware support like Knoppix or SystemRescueCD or Ubuntu), what is the output of lspci and cat /proc/partitions? – Gilles Feb 5 '12 at 21:56
Hi. Its Apacer, P/N: 81.78015.400 | T/N: TB840 |M/N: AP-FM03244B | 200432402936, written on 1 of the Chips: SST|55LD017B|40-C-TQW|0419216-A21 – Email Feb 5 '12 at 23:51
since bios "sees" the chip but in the OS its not visible i am clueless. how is that technicaly possible? – Email Feb 5 '12 at 23:59
Apparently the BIOS has a driver for the chip. This may be a very basic driver, typically slow and read-only. Linux may not have a driver for it, or you may not have found how to access it. Again, what is the output of lspci and cat /proc/partitions? – Gilles Feb 6 '12 at 0:07
