...and a question about XCMOS. I have a 386DX with an AMI
bios, and the memory check has just slowed down by at least
a factor of 2. Also, I just noticed a checksum error in
the XCMOS; saving the XCMOS settings (without changes) cured
this but not the slow mem. check. Are these related? Any
ideas? Thanks in advance for any help!

Thanks in advance for any help! > >Dave Hsu ({...}!decwrl!vlsisj!david, david@compass-da.com) I think you may find an option in your extended CMOS setup thich allows you to change your RAM access mode, at least that's what we have on our 386's and I noticed it more than doubled the RAM test speed at boot time. ----------------------------------------------------------- On the subject of AMI BIOS's can anyone help me with the following? I have an EISA 486/25 with an AMI BIOS giving the following problems: 1. The first 2 Mb of RAM test quite quickly but then the next 10 test at about half that rate. All RAM is SIMMs direct on the motherboard. Under QEMM all the RAM seems to have the same speed. 2. When running DOS, Norton's SI reports only 639k of RAM rather than 640k. It seems the BIOS has nicked the top 1k of RAM. The BIOS does not seem to set up the PS/2 style XBIOS pointers so that QEMM can relocate this 1k of RAM and then give me 736k using the VIDRAM utility. Is there any way round this? AMI are you out there ??????????????????????? Michael Traub BT Customer Systems, Brighton Systems Centre. traub@rtf.bt.co.uk
