And for future references, here's how I found out: 1. On the sources where you have the options highlight one of them and press ? (help). You'll see X86_32 under "Depends on:". 2. Hit ESC twice and then twice again to return to a menu with search functionality. Then type /X86_32 and hit enter. You'lll see that the option depends on !64BIT, so you need to disable CONFIG_64BIT for X86_32 to be available. 3. After disabling CONFIG_64BIT on the kernel where the options where missing I searched X86_32 again and this time it has [=y] next to it so it came on automatically and the options showed up but for some options you need to enable manually after enabling the dependencies. - -- Fernando Rodriguez -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJXkCBTAAoJEPbOFX/5UlwcR8sP/2kwuumtlSymDTyPj4CFS0Q7 noRYWAzutRKDb6GTrobwB5zDVwJTUORuoRE+XXQFeVWRQhjSI2wsaRGL/Cn8duhW QTdgtvrV8T6bdcjftVbeExFvKTDrMXUAEbd+XyRObj7r13454GtYdgOIpktxwDrH D2a3bR2NX7fMxFfSBk4osv3UkoL3xM201MXwUhZgOtTaX/DAw12gSg1ljTJ8UV7O snu+Td9YHcoohrmBpN4yX7uaBL4LnZZnBv59TZekXDv6DGyc70QZO97gNGOvG2SC www7wsM28/hrKqeQI5CNcpl6UvibQGndThld7y1Y5YeByHEBHt31yZp97g1Ira5T 2iadpgoSFiMaCy2+BXfIjktLbIe9E5vH15dVMKxuWazrf7Zf9XszxuU6nZE3RiN5 J9ytAwL/RESjQwB11p3LLf/1zgyYAtIzt/N7QrbvJmHmjj7WyRMK6QCLJsew7izl g/Hjsqvq73QvNdRfjbxTK19sOO1clpJfAdvyHELR+TVvJDAooWFj/8KBfSGCimkv 6bVnDFKIB/ov/o3ZhX121FHq/zH6SH/CxbVozIuTTiowumgftgPMapEiXRIvp/+S ar8dcUF+xiRcKOmx4mBctOxQQ6R0z0o1oWItyjioyB0Rb09kMVjNCQuvq9IpPzLn kl+C7ndrh4etobK9nv2A =fojV -----END PGP SIGNATURE-----
