Question Memory check on soft reboot


Hi all,

I have an old Pentium 90 machine dual booting Linux (2.6.15.5) and DOS/Win95.

When rebooting from Linux the BIOS always does a full memory check at POST; when I reboot from DOS/Windows the BIOS will happily skip this tedious step (a lot of RAM in an old computer) and commence IDE device detection immediately.

I did not find anything in the manpages of the reboot command that would allow the customization of this behavior. Why does it happen? Is it possible to change it (i.e. skip the memory check after Linux reboots)?

I guess it must be a difference in the signal that is sent to the motherboard, but my knowledge in that field is very limited.

It could also be related to the problem in this other thread, since Vector Linux (which I use) is Slackware based:

By the way, the motherboard is a FIC PT-2007, with 256MB of RAM in DIMMs.

Thanks all for any help!

Strange. I would think this is a setting in your BIOS irrespective of OS.
If you enter the BIOS setup you should be able to disable the memory check. Perhaps DOS is sending some signal that Linux isn't as you say, but I don't know a whole lot about BIOS's either.
