My guess is that > 2.1.131 get the logical params from the BIOS and 2.2.0pre5/6 calculates
No, both kernels read the BIOS values. The question is, does your BIOS support beyond the 2.1 GB old limits? Since a CHS=4092/16/63 is exactly 2.1 GB drive which would call Large and not LBA translations.
What is the model of the onboard host-adapter?
By chance is there a disk-overlay flopping around on the drive?
Please send me a copy of the identify
cat /proc/ide/ide0/hda/identify > zaphod.hda
I am curious about the content.
