24102b overburning with Nero

I’m getting ATAPI errors at the end of the overburn (both 5.5.8.2 and 5.5.9.0), but the CD is fine… trying to overburn 80 min CDR to 81-82 min… (should be safe), even with 90 min CDR.
I have Win2k SP2 with its own IDE drivers on i850e board, with Intel App Accelerator 2.2 it’s the same.
What value shoud I enter in Nero advanced settings - overburn? I’ve read somewhere, I need exact overburning limit to enter…

You can do a overburn-test with Nero CD-Speed to se where the limit goes, then enter that value into Nero… Seems strange though with 80min that can’t be overburned even 2min…
