Re: Installer: no option to set geometry/corrupts partition table

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:Hi guys,
:
:I installed the 1.8.0 release from the liveCD and it screwed up my 
:partition table. How can I set the drive geometry so that the installer 
:will use my c/h/s values instead of the (possibly incorrect) values said 
:to be obtained from BIOS?
:
:I noticed this problem in FreeBSD but it seems to have been mitigated by 
:the installer offering a "G" option to set drive geometry around 6.1/6.2 
:release, not sure exactly when.
:
:I posted a question on the users list on Feb. 26 but hearing nothing 
:(and wanting to install Dfly 1.8.0 release) I am posting here on bugs. 
:Someone with a multiboot setup who doesn't track changes to his 
:partition table can suffer loss of data because of this error. It could 
:be a relatively serious problem, especially for newbies to multibooting 
:as symptoms probably won't appear immediately, it will be difficult to 
:diagnose.

:Thanks,
:Rand

    Hmm. usually that sort of problem is due to the disk mode in the
    BIOS setup not being set to Large or logical block mode.  Nobody
    has used CHS in a long time, and BIOSes still get confused by faked
    CHS numbers.
