i was searching the web last night and i found this
"I don't know if you ever found an answer to your question but. I have a Compaq 7110US that originally came with Windows ME 2x128MB PC 2100 and a Athlon Tunderbird 1.33GHz.
The motherboard is a Compaq 070Ch, which is even older than your 073Ch and I'm using BIOS: Compaq 786K2 05/03/2001 which is also older than what you have.
I'm currently running an XP2400+ With 1 256MB stick of Crucial and 1 512MB stick of Mushkin PC2100.
Using XP Home as my OS.
Just today, I popped in 2 sticks of 512MB Kingston PC2700 to test them and it recognized and worked just fine with 1GB of memory installed.
I can't tell you what will work for you but I thought this info might help."
