BIOS Modification - DFI 586IPVG, Cyrix MII 433, K6-2/+ 450

Just re-visititing this post...

In reviewing the data in spreadsheet format, it becomes obvious that the Main RAM Read Speeds are about the same...it is only the Write Speeds that are slower.

At 66MHz (15 nS) and with no caches enabled, the difference is 151 - 90 = 61 nS...or about 4 clocks.

What could introduce a 4 clock "delay" into the Write path only? BIOS wait states? Why would a mainboard designer want to do this?

Hey all -

It's been a while since I visited this thread...mostly because there hasn't been anything new to report. Wink

Well...that all changed a few days ago. Sad

I came home to find out that we had a mini power failure during a storm. No biggie...the DFI just reboots itself and sits there waiting for me to log back in. Standard practice here (after this sort of thing happens) is for me to run a "Chkdisk" before doing anything.

Well...this time it wouldn't pass the "Phase 1" test. Sad

After booting to Safe Mode/Command Prompt, and running Chkdsk from there, I found that the drive has four (4) FRS Errors - Segments 2588, 2589, 2590 and 2591 are unreadable.

The thing is...the PC *seems* to boot just fine.

I'm not planning on "fixing" anything at the moment because I'd like to know just what file(s) reside in this area.

Because the FRS records are low numbered, I'm assuming that they refer to something written when the OS was first installed...though I can't be sure of this.

Does anyone know of a good NTFS MFT FRS reader program that can help me determine what is going on here before I let Windows try to "fix" things?

Thanks.

Thank you for your post DoZe2, but I'm not looking to get anything "back".

Thanks.
