can't text install with 16 MB RAM (not enough RAM)

From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.2.18 i686; Nav) Using the bootnet.img, the installer boots fine, but judges the system short on RAM. Supposedly 16 MB is the current minimum, which this machine has. Hardware is known good on previous version of Redhat: 486/AMD 120MHz Reproducible: Didn't try Steps to Reproduce: 1. Make boot Image 2. Boot 3. Choose text install Actual Results: Dialog box "This machine does not have sufficient memory" or something along those lines. Will verify actual text and update I am confident the kernel is finding all the RAM, it's just a matter of the calculation.
A few questions: 1) How much ram does the machine have? 2) How are you sure that the kernel is seeing all the RAM? Try booting with saying something like 'linux mem=32MB' or however much ram you have to make sure that the kernel sees all the RAM.
1) The machine has 16MB of RAM, ONLY 16 MB of RAM. 2) I'm confident it is not a matter of the kernel seeing the RAM. It's a machine that at one time had more RAM running Redhat 4.2, not a problem. I'm assuming the minimum for install is 16 MB RAM.
No, you need more than 16MB for the 2.4 kernel to run with acceptable performance. Anything above 16 MB is ok, so 17 MB is the minimum that the installer allows. If you look in isys.h in the installer: #define MIN_RAM 17000 /* 20M or so */ If you know how to modify the installer, you can force it to ignore the amount of RAM. Try booting with 'linux mem=20M' and see if you can get text mode install to work. Don't be surprised, though, if the installation crashed becuase the kernel runs out of memory and kills the anaconda process. :)
