FreeBSD fdisk reported some very large numbers and negative numbers for the cyls, heads and sectors, along with the kernel error messages. DOS fdisk reported 6136 x 16 x 63 = 504MB. > What did the probe report to you? The kernel proble reported the same parameters as your disk. I tried flags 0x80ff80ff and 0x0 and got the same result. boot: -v looked normal, no addtional message when probing the HDD. > What were the settings in the BIOS? 6136x16x63 NORMAL. ( I also tried LBA on/off, 32-bit access on/off, block reading on/off, PIO mode 0/3/4 on Pentium and P Pro). The 486 computer doesn't have these settings.

A Wintec (Edom) Pentium, Award BIOS and a Xinetron 486, AMI bios. Thank you for your comments. The hard disk is no in my hands now so I can not do further experiments on it :-( > > > Later...... <Doug> --Jason --------------------- Jason Liao <jasonl@xinetron.com> ---------------------
