I have the Gentoo Installer running on my Thinkpad Pentium M 735, and a |
| 2 |
few things caught my eye. The 735 is a Pentium M |
| 3 |
(http://intel.com/products/processor/pentiumm/index.htm), so I selected |
| 4 |
Pentium-M as the architecture type on the gcc config tab. I was |
| 5 |
wondering about the discrepancy. |
| 6 |
|
| 7 |
TheCXXFLAGS value doesn't seem customizeable (CFLAGS is set to the |
| 8 |
values I set). And further down is what is configured during the |
| 9 |
Install's kernel config (MPENTIUM4 is chosen instead of MPENTIUMM): |
