I bought a new PII/300 with 128MB (single DIMM) and AGP. I orginally had Win95a on it. It did see 128MB. I found out that 95a does not understand about AGP so I used the OEM 95b CD-ROM and USBSUPP to upgrade 95 to OSR2.1. Everything works great except that Win95 only sees 64MB of my 128MB. Both the MEM command and the 95 General screen show 64MB. Oddly enough, the Supermicro motherboard CMOS shows 128MB and booting from a Win95 OSR2.1 startup disk shows 128MB using the MEM command. Only booting from the HD has 64MB. Even "Safe Command Prompt Mode" shows 64MB so no drivers can be involved. I verified the startup disk IO.SYS was the same as the HD version.
Any help to make Win95 see the rest of my memory would be appreciated. Thanks.
