Bad documentation on XP installs for T400
Posted: Fri Sep 21, 2012 9:59 am
Anyone who has any notions of what to do with this info? Purely by direct observation. In any case, it's verifiable:
Lenovo would have you do the F6 stuff and use an A: diskette with the IMSM stuff on it to prevent the BSOD crash and that works per se, but I have an important distinction to report:
If you instead install in compatibility mode and follow the directions to AFTERWARDS set it to AHCI and then reboot and provide the driver info [either their way or with a diskette, whatever] there is actually an important difference between the two results. [They falsely claim they are identical ways to get to the same place, but it's just not true]:
If you do the recommended procedure, that XP system will BSOD on every bootup if you set the BIOS to compatible SATA mode while doing it the way that starts with compatible mode will in fact boot with the BIOS set to either Compatible or AHCI. If you are like me and use bootable CD a lot, it's a needlessly larger PITA problem because you have to remember to switch to Compatible when booting the CD and then change it back to AHCI before booting to the hard disk, etc. If there are several iterations involved, you have to make twice as many BIOS changes, thus the compatible mode-starting install is clearly not identical to the F6 start method, it is superior.
Thus, if you read their doc literally ["they are equivalent"] you aren't really there.
So far I haven't been able to figure out how to remedy this; you're stuck with the inferior install unless you literally start over again [perhaps a repair install, but that doesn't always work; would be a bit foolish to risk that over this silly an issue.
If you noodle around the PREPARE directory there seems to be some undocumented files, but this may be irrelevant. In any case, some of us have elaborate installs that don't want to be paved over; too much work, etc. but is there any way to get there without a repair install?
[Of course for any new work I just use it the compatible way which always works; after all, it is documented as "identical" isn't it?]
cjl [so this is at least a word to the wise, but also a plea for help to remedy what a missing step might look like; solving this can turn into a demand for replacement documentation that these are actually NOT identical as written or if figured out amend it so they then would actually be what they claim it is, etc.]
