RedHat 5.0 only recognizes 16 of 32 mb of RAM

RedHat 5.0 only recognizes 16 of 32 mb of RAM

Post by Brad Fiel » Sun, 21 Jun 1998 04:00:00



I'm a Linux newbie  and I am having trouble with getting RedHat 5.0 to
recognize  more than 16mb of my 32mb of RAM. When I first installed it
the system  saw all of it, but now every time I boot up it only sees
half.  I have a home made system with a P150 Cyrix processor and  I use
generic edo simms.  The BIOS  sees all 32. Additionaly, I run win95 on
another partition and it sees all of it too.  I tell you, I'm running
Netscape 4.05 with 16MB and it runs like a dog. I would appreciate any
advice any one can give me.

Thanks...

Try redoing your kernel and tell it NOT to limit memory to 16 meg.

1. Q: SLS 1.01: only 16 MB of 32 MB swap partition recognized ???!!!

Following Problem:

I have a 32 MB swap partition configured as partition sda7.
Linux seems to recognize only 16 MB ?!
I use SLS 1.01 with the kernel 0.99 up to PL 9 (if I remember right).

My Partition Table:

Disk /dev/sda: 64 heads, 32 sectors, 639 cylinders
Units = cylinders of 2048 * 512 bytes

   Device Boot  Begin   Start     End  Blocks   Id  System
/dev/sda1   *       1       1     150  153584    6  DOS 16-bit >=32M
/dev/sda2         151     151     639  500736    5  Extended
/dev/sda5         151     151     161   11263+   6  DOS 16-bit >=32M
/dev/sda6         162     162     182   21503+  81  Linux/MINIX
/dev/sda7         183     183     215   33791+  82  Linux swap
/dev/sda8         216     216     336  123903+  81  Linux/MINIX
/dev/sda9         337     337     639  310271+  81  Linux/MINIX

Swap setup:     mkswap /dev/sda7 33791
Use swap:       swapon /dev/sda7

Swapon reports during "adding of swap space"
that I have (only!) 16 MB swap.  Free reports the same !

             total       used       free     shared    buffers
Mem:         14716      10500       4216       2236       6144
Swap:        16380          0      16380

What about mkswap, do I have to type in
the number of 512 Byte blocks if I do an mkswap command ???!!!!
..... mkswap /dev/sda7 67582   !!!?????

Seems to be, although I'm sure that mke2fs uses 1 k block sizes as
argument !!! A bit wired !!

        Thanks in advance

3. X slows down with more ram (16 -> 32 mB)

4. ViewSonic 17PS - STB Velocity 64V

5. Open Sesame

6. Pentium with 16 Meg ram or 486 with 32 Meg ram

7. P^3

8. can redhat 7.2 run *comfortably* on a P-I 166 Mhz / 32 Mb RAM system?

9. 16 MB of RAM detected instead of 90 MB

10. Cirrus CL-5434 vid card, 16 MB RAM, and 16 bpp under X

11. 16/32 Mb video card recommendations

12. 16 -> 32 MB memory upgrade makes system slow
