The font you shared previously wouldn’t load and was saying corrupted when I tried to add it.

it takes a few minutes to launch as you may imagine it’s working hard.
I wanted to attempt to skip some of the hardware not present.

I doubt doing -NOACPI -NOPCI -NOSMB will make much difference, either way if there is a lockup I would prefer to fix it.

If really needed I would do SIV32L -NOACPI -NOPCI -NOSMB then Menu->File->Save Selected as this would mean the SIV start-up + per section times would be in the save file.

Actually yes I do have a couple of MCA systems but I’m a little time limited to do exhaustive testing.

Looking at your profile I guessed as much. AFAIK SIV has never run on an MCA system, I suspect/hope it does OK.

Full run - i installed the fonts and they appeared to work - do you need the additional cpu check as well ?

Thank you, most things are now as I would expect, but the CPU type detection, speed and L1 cache size are strange, doing the additional CPU check should tell me why.

SIV should have reported IBM 486BLX2 and I can't see why it didn't, please do SIV32L -DBGCPU -EXIT=20 > SIV_DBGOUT.log and post the .log file.

The AAM is used to measure the CPU speed and for IBM Blue Lightning it takes 17 rather than 15 cycles, allowing for this 65.1 * 17 / 15 = 73.78 which is still low, please post a screen shot of Menu->Help->Conversions->CPU MHz so I can see what get's reported.

Comparing your system to a Cyrix Cx486DLC @ ~33 MHz it's much slower, I wonder why?

On a different IBM 486BLX2 @ 66MHz as below was reported.

Looking at [Cache-0 Latency] the time for 16KB is much the same as for 24KB, are you 100% sure the L1 cache is enabled in CR0 (Control Register 0) ?
