The BIOS on the compaq does not support your 20GB Harddrive, you will have to buy a Promise IDE controller ($50) to solve the issue with 8.4GB only showing up.

The memory is probably not supported either. You need a single sided 32MB module. The 64MB Module is double sided, 32MB on each side, and the memorybank only support singlesided memory.

The BIOS has limitations for HD size, which will prevent detection of a new, large drive. Set auto and use 8GB, or try updating the BIOS. Setting parameters manually may not be the best way here. Check if the computer needs to have BIOS partition on the hard drive (manual or Compaq site).

This computer may have special demands as to RAM type. You may have to buy Compaq modules or find older 32M units and put in the system.

Here is the answer for the memory ftp://ftp.compaq.com/pub/supportinformation/consumerdocs/Consumer_QRG/presario4500.pdf

For the harddisk issue, what model of harddisk that you had brought ? The solution is 1st u need to upgrade the BIOS. Even after upgrade also shows 8.4GB doesn't matter. Let it be. The important part is u need to download the disk manager for that particular model of harddisk.

For example if u brought a Westren Digital harddisk u may need to go to http://www.seagate.com/support/disc/drivers/discwiz.html for seagate harddisk and http://support.wdc.com/download/dlg/dlginstall_10_0.exe for western digital.

I did install a lot for my customer, it works all even is 486 PC.

presario 4506 is only support max 48MB of RAM.
and very picky about which RAM to use. So suggest your need to verify the ram before buying it. www.crucial.com or http://www.memoryx.net/presario4506.html both sell those. I believe SamSung has some disk manager program  you can download that can help your BIOS recognizes 20GB. You need to know the model of SN of the HDD to download it.
good luck
