Hello, This may be a stupid one but I'm scratching my head on it, so here goes: I have just added some RAM to my P133 machine and it now totals at 72MB. However, Linux (2.0.30) only sees 64MB. BIOS reports 72MB correctly. DOS also sees 64MB (!). What am I missing (at this time of night)? Why would the OS's see 8MB less? The MB is documented to support upto 128MB. Thank you! Doron
