[Attached full log of LinuxBIOSv2 output.]

Error #1 of 2 (DRAM Succeeds):

Ok.  I've set the following in tyan/s1846/auto.c:

        /* Check 64 MB of RAM. */
        /*ram_check(0x00000000, 0x04000000);*/
        ram_check(0,0x9ffff);
        /*ram_check(100000,TOM);*/

Should I try also (100000,TOM) or is it satisfactory once DRAM succeeds?
