First of all, I'm not expert in these matters. I'm
just curious why I can install 4.11, but not 5.3.
(I wish I could install 5.3 !!).
Indeed, the BIOS is a strange issue.
In the BIOS setup, I can select
1) Standard CHS
2) Logical block
3) Extended CHS,
4) Auto Detected
But whatever I select here, when I get back into the
the BIOS setup, to verify check my settings, I
find that 1) is selected. Apparently this is what
means "disabled by BIOS", but I'm not sure.
The 4.11 dmesg output has following:
------------------------------------------------
CPU: Pentium/P5 (55.18-MHz 586-class CPU)
Origin = "GenuineIntel" Id = 0x517 Stepping = 7
Features=0x1bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8>

atapci0: <RZ 100? ATA controller !WARNING! buggy
chip data loss possible> at device 1.0 on pci0
atapci0: ATA channel disabled by BIOS
-//-
ata0 at port 0x1f0-0x1f7,0x3f6 irq 14 on isa0
ata1 at port 0x170-0x177,0x376 irq 15 on isa0
-//-
ad0: 520MB <ST3660A> [1057/16/63] at ata0-master
BIOSPIO
------------------------------------------------
Notice that the harddisks are on isa0, not on
atapci0; probably because of this buggy chip and/or
BIOS problem.
Could it be that 5.3 install cannot (yet?) handle
harddisks on isa properly?
Or must I help 5.3 by setting some hints/syscontrols
before loading the kernel?
Thanks,
Rob.
