Actually it is -- dare I say it -- even more simple in grub2 :) |
| 30 |
|
| 31 |
menuentry "Memtest86+ 4.20" { |
| 32 |
linux16 /memtest86plus/memtest.bin |
| 33 |
} |
| 34 |
|
| 35 |
That's from my grub.cfg... I don't use the grub auto-configuration |
| 36 |
tools. I just made a manual grub.cfg like in the grub1 days. It is |
| 37 |
quite similar to the old grub syntax, but more can do more stuff. |
| 38 |

BTW there is a new version 5.00 of memtest86+ which is on rc1 release |
| 40 |
right now, it supports multi-core processors (and tests/uses them), |
| 41 |
shows system temperature while testing, is much faster than the old |
| 42 |
one, and has a few new tests. There is a link to it on the memtest |
| 43 |
forums. |
