Anaconda doesn't recognise Gateway Solo 9150's LS-120

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020607 Description of problem: When anaconda prompts me for a floppy, it is unable to read my floppy because it thinks it's in /dev/fd0. Unfortunately, I have an LS-120, so /dev/fd0 is disabled after boot. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Get a Gateway solo 9150 (laptop) with a combined LS120/DVD-ROM module. Alternatively, ask me to test the image. 2. Boot anaconda, have it ask you for a floppy to read. Actual Results: It attempts to read device 02:00 (/dev/fd0) and fails because that was disabled after boot. The image is now at /dev/hdd (my LS120 drive) Expected Results: It should have noticed at boot time that I had an LS120 and known to look there. Additional info: This has happened once before, and as I understand from Jeremy it's because the LS120 on my machine is identified by the kernel with a different string than the (normal) LS120 drives Red Hat tests on (and than it used to when he last fixed this problem). Since it has broken again, Jeremy's guess was that it's a matter of the kernel changing how it identifies the drive. So here's what the kernel says about the drive at bootup: ... ide1: BM-DMA at 0xfcd8-0xfcdf, BIOS settings: hdc:pio, hdd:pio ... hdd: LS-120 S200 01 UHD Floppy, ATAPI FLOPPY drive ... hdd: No disk in drive hdd: 123264kB, 963/8/32 CHS, 533 kBps, 512 sector size, 720 rpm if there's anything else you need, please let me know. Unfortunately, I can no longer work around the problem, so I need this to be fixed :-/
What is the output of python -c "from kudzu import * ; print probe (CLASS_FLOPPY, BUS_IDE | BUS_MISC | BUS_SCSI, PROBE_ALL)" Also, what's in /proc/ide/hdd/*?

Could you look on VC3 after you are in the loader and see if there is a line like: system floppy device is xxxx where xxx would be /dev/fd0 or something similar? Why does there appear to be a fd0 controller but no actual drive? Is the fd0 disabled in BIOS?
There is such a line. It says: * system floppy device is fd0 Not that that means anything. From what I've been told/I understand, LS-120 drives work like this: At boot time, the LS-120 drive emulates/enables a floppy disk controller so that the system BIOS can use it to boot. Thus you can pop a floppy into the LS-120 drive and boot off the floppy as if the drive were a normal floppy drive. I've never tried it, but I wouldn't be suprised if you can't use an LS-120 disk to boot simply because the floppy disk controller/BIOS doesn't support LS-120 disks. So, yes, the system floppy device *WAS* fd0. However: Once bootup is complete, the floppy controller is disabled/ignored (by the drive, I would imagine, since I'm guessing it's purely a compatibility measure). At this point, any attempts to read/write disks via the floppy controller (fd0) will always fail because the drive has simply stopped listening. Instead, requests must go to the IDE chain (hdd). So, no, the system floppy device *ISN'T* fd0 any more. The bug, to reiterate, is that the installer/loader doesn't recognise my LS120 drive as such and realize that it needs to invoke the (already coded) LS120 workaround to get to the floppy it's requesting.
*** Bug 70350 has been marked as a duplicate of this bug. ***
Should be fixed now
We are able to make use of an LS120 drive here at the office, so we think this is resolved. Unless you have something "special" going on, in which case, please reopen and we will research more and attempt to obtain the hardware in question.
