>Description:
I used 5.4 before in the old machine with Pentium 133, 128MB ram, and
a PCI SCSI card(PCscsi II AM53C974AKC) with a 2GB harddisk.

I installed 5.4 with 5.4 iso CD long time ago, the 5.4 works very well
in the box.

Now I want to change all the system to 6.2.

Downloaded 6.2 iso files from FTP, burned them to CDs. I tested the CDs
on other machine and virtual machine, it works well.

While I try to boot the old machine with that PCscsi II SCSI card, it
panic on booting. Or it might not call panic, I saw lots of same stuffs
scrolling the screen, looks like some register name and value display
continue on the screen, and the keyboard locked.

The display stuffs looks like:
esx=00 00 22 11 44 55 00  asx=00 22 33 55 66 99 99

I facked the values and the length. It scrolling too fast, I can't see
it clearly.

If I unplug the PCI SCSI card, it boots ok. I also tried to plug the
card in different PCI slots, but they are the same, no lucky.

I also tried 6.1RC CD which I burned before, it cause the same result
with 6.2.
>How-To-Repeat:
Pluged the PCscsi II AM53C974AKC PCI card into slot, boot with 6.1RC
or 6.2 CD.
>Fix:
Unplug the SCSI card, it means don't use it!
