Slackware install iso where is the 64bit for BIOS


Installed 32 bit 14.2 on my desktop but have trouble putting it on my 64 bit laptop where Ugh! Fedora28 resides.
This is 2 problems so will create a second query for the UEFI later.
PS Installing from DVD and yes Fedora still works.
Downloaded 64 Slack ISO but saw no designation whether it was for BIOS or UEFI until I finished putting sdb2 on partition 2. It then asks me to setup EFI on partition 1 where I installed SWAP. How can I determine which iso is 64 bit and BIOS as I intend to turn off EFI and use BIOS because of problems I had with UEFI in the install (something about moving /EFI/boot... and renaming it on the EFI partition but that is the other problem).
I think I turned off the UEFI when attempting the BIOS version install. Anyway
it seems to be a problem with the downloaded BIOS version of 64bits. How can I tell which to download?

There is only one Slackware64.

Efi or not is the way you will boot. Check if you have efi only or legacy only or both configured.

If legacy, use lilo.
If efi I would go with grub.

Both are part of full Slackware install.

If you need help to install, try to write what you need to do clearly.

As Tonus mentioned, there is only one Slackware64. It supports both BIOS (legacy) and EFI booting. Now, it will only present you lilo or elilo options in the installer based on how you boot it, and this is different depending on your firmware. For my two UEFI systems I've used, when I go to select the boot items, it will present me with two Slackware options, UEFI and legacy, and I can choose which one I want to boot. But this is only if I enable the CSM (compatibility support module) option, which is basically enabling the legacy (BIOS) booting ability. I've heard that some systems will only present you the EFI option if CSM is disabled and only the BIOS option if it is enabled.

If you boot it in legacy mode, it will only present you the option to install lilo. If you boot it in UEFI mode, it will ask if you want to use elilo.

As for it asking you to set up the EFI partition on your swap partition... it suggests partitions based on partition types. If it presented partition 1 to be your EFI partition, then the partition type was probably marked as an EFI partition (or possibly formatted as FAT32... I don't remember exactly how the installer determines that). You would want to use fdisk and change the partition type to be 19, Linux swap. EFI partition type would be 1. You should also be able to do this with gdisk, cfdisk, and cgdisk, but I'm not as familiar with those.

ThanX 2 both!! If I understand U all set it to CSM for BIOS and UEFI instead config-ing if I installing UEFI off of the same ISO DVD. Why did I get it trying to create UEFI on partition 1 when I had config'd that partition 1 to SWAP when doing install for BIOS? I don't get further than that thinking I will clobber something when trying to install for BIOS. Will try over weekend. TNX

I would check and see what your partition type is listed as for partition 1.

You can do that with fdisk by running fdisk against your device, fdisk /dev/sda, then pressing 'p' and seeing what it lists as "Type" for your first partition. If it was configured as swap, it should show "Linux swap". If it doesn't show that, you can change it by pressing 't', selecting the partition, and then typing in the Linux swap partition code, which is 19 (you can verify this by pressing 'l' to have it list all the different partition types).

Tonus@ Have tried firmware setting=UEFI (same as when setup Fedora 28) with Slackware-64 install disk and partition 1 as Linux UEFI, 2 for swap +5G, plus 3 for the last partition of about 23G. Result is Kernel Panic when I booted.
Can't recall stipulated reason. Familiar with Slack installation since about '96 and do recall that it was NOT an obvious install related.

For 32 bit DVD version on my desktop 32bit machine works OK, sans some missing games but will use pkgtool for that probably due to removing about 32 of the games. Attributing Wallet being icon-ed as marble to similar condition.

Laptop is Toshiba Satellite A-5126 currently uses Fedora 28 no install problems.

Over weekend with firmware=CSM and 64bit install DVD got partition 1 & 2 accepted for fstab then it wanted UEFI made on /dev/sda1 <--!! WHAT! Stopped it there must leave M$ Windoz as needed when explaining how slackware is better. Definitely built partitions 1 & 2 on /dev/sdb!! per "p", on the flash drive.
Did not get as far as LILO/ELILO. PS when booted in UEFI I skipped LILO offering and went for ELILO only fwiw.
I used fdisk to set up partition tables and wrote them to disk in all cases. fdisk displayed both partitions as Linux system (or what ever the non-swap term is for that on both and DOES NOT allow "t" option to name the type. Therefore used cfdisk to append Linux Swap type on partition 1 and wrote again.

In just re-reading "bassmadrigal's" note again the failure on 64bit laptop for UEFI might be a forgotten typing of
partition 1. Will retry and inform. That leaves, for now, why it wanted installing UEFI on partition /dev/sda1 (sdA1)? when building for BIOS/CSM for 64bits.

bassmadrigal@ How did you get a partition type of 19?? The swap type is 82(00), see cfdisk "TYPE" list and for as
long as I remember (oops that may not be justification, giggle)
Thanks again to both of you please respond if you have further suggestions.

It looks like this probably depends on the partitioning tool used. I am pretty sure fdisk used to be type 82 for swap, but on 14.2, it is now listed as 19 (no clue when that changed). Make sure you just follow the type code for the partitioning tool you use (and if it is 82 in cfdisk, make sure you stick with that).

Just a thought :
Does Fedora still boot?

If yes then there should be a working bootloader that just has to point to Slackware too...

Otherwise, what I usually do to fix such problems is boot with a USB distribution (AlienBob's slacklive of course) then chroot into installed slackware (with efi partition under /boot/efi) install grub if needed, make initrd with mkinitrd and update grub with grub-mkconfig.

If you need help on how to chroot or pass commands just ask (did not write every details since I am posting from phone).

BTW, booting with slacklive will show you if efi is used (grub bootloader) or not (syslinux bootloader iirc).

Hi,

I suggest that you look at; http://docs.slackware.com/start
to help you with installing and any other issues. Loads of information and the site is searchable.

Hope this helps.
Have fun & enjoy Slackware!

bassmadrigal@ Thanks but use cfdisk when I select type. So that would use the correct type regardless of number being 19 or 82 or 9999. But can't see what fdisk uses for a type number since l list scrolls off why I use cfdisk.

SqdnGuns@ for 32bits BIOS it is LILO. for 64bits UEFI it is ELILO. for 64bits CSM (aka BIOS) it is LILO.
Using a detailed step by step install instruction set which I bring up on my desktop and follow it to the letter it is much more detailed. GRUB vs cfdisk vs fdisk should NOT matter.

Here is my problem with firmware set to CSM (aka BIOS), using 64 bit laptop I get all installed via my step by step list so I don't miss and for UEFI set in firmware on 64bit on booting I get "Kernel Panic - not synching: VFS: Unable to mount root fs on unknown - block (0,0).
Since install proceeds without a hitch in either case in either case and step sequence ends in an OK I am lost for the first time in over 20 years. Installation on my 32 bit desktop works no problem thinking I have a problem with Toshiba C55-A5126 64 bit laptop.
Will be switching to Fedora (UGH!) to teach 2 classes after 1st of the year. Have to be able to put it on flash drive so I will not be blamed when the students overwrite their hard drive and pre$$ious Windoz$. Never had such a problem with Slack in all this time.
PS installing from DVD and yes Fedora is still working it is also on a flash drive.
