sementation fault slackware 9.0 on 486


Hi im trying to install slackware 9.0 on a 486dx2 80mhz with 16mb of ram and a 1gig hdd. There are two problems I am having. First is when i boot from floppie disks the first disk works fine (bare.i) but the second disk (install.1) dosent allways work and says:

crc errir<5>VFS: Insert root floppy and press ENTER

then when i try again it says

FAT: bogus logical sector size 2461
UMSBOS: msdos_read_super failed, mount aborted
FAT: bogus logical sector size 2461
FAT: bogus logical sector size 2461
read_super_block: can't find a reiserfs filesystem on (dev 02:00, block 64, size 1024)
read_super_block: can't find a reiserfs filesystem on (dev 02:00, block 8, size 1024)
Kernel panic: VFS: Unable to mount root fs on 02:00

and crashes. I can get around this by changing floppy drives around, but I can't use the same one twice unless I leave the computer off for a while. I have no idea why this works.

But the main problem is that when i get it to boot it says segmentation fault when i log in as root then again when I try to install the files.

If someone can help me with this I'm not really sure what segmentation fault refers to Ive tried a few different hdds and ive used the same floppy disks, floppy drives, cdrom and slackware cd I used on a 486dx2 100mhz with 16mb ram and 1 gig hdd a few days ago and it installed fine.

thanks

A segmentation fault, or signal 11 as it is sometimes referred to, is a nasty problem because it is hard to determine its source. What it means is that a program tried to access a block (or segment) of memory that does not exist, hence the name segmentation fault.
Usually it is caused by poor programming, but this is something we can rule out in this case. It can however also be caused by a variety of hardware problems. Bad memory blocks, memory too slow, or even CPU temperature.
Some motherboards have an option called a "Memory gap" (also known as LSB support or memory hole), this means that 2 Mb of memory just below 16 Mb are mapped out. If you have this option in your BIOS and it's turned on, then that might very well be the cause. There is however a host of other possible causes, all related to internal data transfer.

Finding what is causing your segfault can be a real pain in the behind, this page has a pretty exhaustive overview of all possible causes for a segfault.

I sure don't envy you right now....

Thanks, that was a good site too. I set the bios to defaults and that fixed the floppy disk problem then i swaped one of ram sticks and it fixed the segmentation fault. Funny though the ram that was all rusted and corroding wasnt the faulty one.
