Hi Vijay

I thought youa re one of my collegues from Chennai
Anyway, nice to hear from you and to get confirmation that my "old" problem
was not only in my dreams!

I totally agree with you and found that the problem is live upgrading from
brezzy to Dapper (previous version was working properly) and still life in
6.10.
I'm not a specialist, but even upgrading Bios and changing motherboard to
ASUS A8N32 - SLI Deluxe, the problem is there.
I cannot imagine a problem from motherboard (one never know anyway)
System is working properly with XP (the only thing probably which is working
properly with XP!)

But I found also that disconnecting a front panel IcyBox with 8 slots
reading memory cards is removing the problem at boot. After boot, hot
plugging the IcyBox, everything is working. Probably it's only a booting
problem.

Kind regards
Marc
