Default CV64 RAM
How do I find out whether my CV64 has 2 or 4MB on board? According to the BBOAH they came in 2 or 4MB flavours, and I want to know whether mine has enough video RAM for 1280x1024x16 (which would use 2.5MB of RAM)

SysInfo reports the board size as 0kb! Bizarrely, ShowBoardsMUI reports it as 64MB :-?

@AMIGAZ
I've got several empty brown sockets on the card. Are they the video RAM sockets?

Great! :-D So what type of chip do I put in the sockets? I think I counted 4 empty sockets so I assume I need 4x512k chips? But what type? Also does the card autoconfig the RAM or do I have to set a jumper to tell it how much to use?

A long time ago I had a 1Mb S3 Trio and I desoldered 2 ram chipsoff a cirrus logic card, and put them in its spare sockets to get 2Mb.

I guess look for a similar old card with 2mb on board in the right config and pinch the chips.

look at the soldered 2 megs already installed and look for 4 identical chips:

814260-70 (FUJITSU)

not that easy to find in small quantities

@Framiga
Have already tried to find the same chips but can't find them for sale anywhere. See my post above - think I might have found a card with some compatible chips on but just need confirmation before I buy it.
